Our Approach
the custom fit approach
At Custom Fit SF, we believe real transformation requires more than a workout plan — it demands an integrated, personalized system that combines training, testing, nutrition, and recovery. Our approach is rooted in data, driven by expertise, and refined through years of helping people move better, feel stronger, and live with greater vitality.
We start with a deep understanding of your body — because that’s where precision begins. From DEXA scans that break down your body composition, to VO2 Max and Resting Metabolic Rate (RMR) testing that reveal your physiological engine, to 3D gait analysis and VALD force plate diagnostics that analyze how you move — everything we do is informed by evidence, not guesswork. These tools aren’t reserved for elite athletes. They’re here to give everyday humans elite-level insight into how to train smarter, eat better, and recover more effectively.
But we don’t stop at the data. Your results are guided by a multidisciplinary team of coaches, registered dietitians, physical therapists, and performance specialists who collaborate to build a strategy around your goals, preferences, and lifestyle. Whether you're here for one-on-one strength training, custom meal planning, advanced bloodwork analysis, or a full lifestyle overhaul — we meet you exactly where you are and give you a plan that evolves as you do.
We don’t believe in one-size-fits-all. We believe in personalized solutions.
Everything we offer — from our personal training programs and partner workouts, to our nutrition coaching and science-backed recovery room — flows from our mission: to elevate human performance and health through intelligent, personalized systems.
If you’ve ever felt stuck, unsupported, or underserved by mainstream gyms or templated plans, the Custom Fit Approach is your answer. It’s not about doing more — it’s about doing what matters, with expert guidance and measurable results.
This is fitness. This is data. This is real coaching.
This is Custom Fit .

DEXA Scanning
Our on-site DEXA (Dual-Energy X-ray Absorptiometry) scans are the gold standard for measuring body composition—including fat mass, lean mass, and bone density—with clinical-grade accuracy. We use DEXA not only to assess starting points but also to track progress and inform training and nutrition adjustments.

DEXA scans are ideal for anyone looking to make meaningful, measurable change in their body composition or performance.

VO2 Max + rmr testing
We offer advanced metabolic testing to help you understand your physiology on a deeper level. Our VO2 Max test reveals your aerobic capacity and training zones, while the Resting Metabolic Rate (RMR) test measures how many calories your body burns at rest. Together, they give us a complete view of how you use oxygen and energy—allowing us to fine-tune your training and nutrition plan for fat loss, endurance, or performance. These tools transform guesswork into precision for athletes and everyday clients alike.

3d Gait Analysis
Our 3D Gait Analysis goes beyond what the eye (or camera) can see—capturing every joint angle, stride length, and movement pattern as you run. Using 3D motion capture technology, we assess how your lower body moves in real time to identify asymmetries, inefficiencies, or compensation patterns. Whether you’re an avid runner, recovering from injury, or looking to improve performance and prevent future issues, this data helps us design targeted strength and mobility interventions. It’s one of the most precise tools in modern movement analysis—and it’s available right here in-house.

Our team

Born and raised in Oregon, fitness and athletics have always been a part of my life. From water polo to powerlifting to yoga, I view the diversity of my personal experience combined with science, proper nutrition, and education as the foundation for my approach to fitness.
As a personal trainer, I recognize that everyone has a different concept of fitness and it’s my job to use my experience and knowledge to safely and effectively get results. Simply stated, I opened Custom Fit to provide the absolute best personal training and nutrition services available. We all follow a training protocol that has a primary focus on core strength, functional movements, correct form, and proper nutrition. From there, each program is custom fit to you and your goals, which we will track to show progress. Our objective is to help you achieve your goals as efficiently, safely, and as easily as possible.

I was born and raised in Las Vegas, where I grew up playing a variety of sports. My passion for health and fitness sprouted at a young age, leading me to move to San Francisco in 2012 to pursue my degree in Kinesiology. I’ve gained a lot of experience training both in a gym setting, as well as working in a physical therapy clinic. I try to combine my passions for health, fitness, and wellness to lead safe and effective workouts for everyone. I firmly believe that fitness is a great way to train the body and mind to make the best version of yourself that you possibly can.

Hello, I’m Alysha, a Registered Dietitian, personal trainer, and motivational coach with a deep-rooted passion for food and movement. Growing up on a farm, I learned about the origins of the food on our table and spent hours in the kitchen with my grandmother.
When I became ill in high school, my perspective shifted, and I began to see food as medicine, recognizing its ability to energize and support our bodies. I now love modifying recipes to meet different dietary needs, proving that nutritious food can also be delicious.
My practice today combines my experience as a dietitian with my background in personal training to guide clients toward their performance goals. My own love of movement began with weightlifting during undergrad, and I’m currently enjoying the world of triathlons.
My approach focuses on delivering evidence-based nutrition strategies, promoting optimal physical performance, and fostering a strong, positive relationship with food and movement.
I take a holistic approach to counseling, focusing not just on nutrition but also on movement, sleep, stress management, and hydration. My goal is to empower you to make food you love an integral part of a balanced and fulfilling lifestyle. Together, we’ll work toward overcoming any barriers and creating a path to optimal health and wellness.

My background in nutrition started in the sports world. I grew up with an athlete as a father and watching him nourish and train his body for performance taught me the power of nutrition on performance outcomes. When I went to college, I discovered my passion for human biology and disease prevention through behavior change. This lead me to dive deeper into science and medicine, pursue an education in nutrition and become a registered dietitian. Through my experiences working in clinical research and private practice I continue to be amazed at what the human body and mind are capable of. I love working with people to discover new ways to improve their health, eliminate barriers and enhance their overall wellbeing and sense of empowerment. I sincerely believe that we can all unveil a brighter, happier self with the power of nutrition and delicious food!

Food and cooking has been a lifelong passion of mine. Growing up, my mother was a dietitian, so we always had an emphasis on eating healthy and balanced meals. My Greek background allowed me to learn a lot about the Mediterranean diet as well as the importance of enjoying meals with family and friends. Born and raised in the Bay Area, I love learning and being immersed in the inspiring and innovative food scene that we are world famous for. Before studying to become a nutritionist I worked in the restaurant industry for 10 years, so my passion for food is not only focused on health, but being delicious as well! I love learning, researching, and testing new recipes that utilize local and seasonal ingredients, are easy to make, and most importantly taste great. I truly believe that healthy, nourishing food can be enjoyable and designed to fit into everyone’s lifestyle, regardless of time, finances or skill.

The more I learn about nutrition, the more I realize how foundational food is in living a balanced life and performing your best. With so much misinformation on the internet and social media, it's become impossible to decipher what's right, wrong or somewhere in between. My goal is to use evidence-based research to help those around me unlock their maximum potential through the power of nutrition and consistency.
After working with Stanford's Sports Nutrition team, and seeing the power of nutrition in sport, I knew that I wanted to pursue a career in sports dietetics. As an avid surfer, I've been able to use my knowledge and experience to improve my own eating habits around performance and daily living. Along with consistent training, mindful practices like yoga and meditation, and a balanced approach to eating, I continually see improvements both in and out of the water.
When we nourish and treat our bodies well, we get the most out of ourselves. So no matter the sport or hobby, whether you want direct coaching, nutrition education or just want to talk about food, I truly look forward to connecting and helping you reach your goals.

My passion for nutrition began during my time as an acrobat in Cirque du Soleil. Before retiring, I became a personal trainer and health coach, and then moved to Australia.
Over the following years, I realized the immense benefit of combining nutrition with fitness to help my clients achieve their goals.
Upon returning to the states, I worked in various established gyms and in corporate fitness, before starting my own personal training and health coaching business.
Simultaneously, I pursued a degree in Nutrition from San Francisco State University. As a Registered Dietitian, I believe in a holistic health approach. It is important to address not only nutritional needs but also to consider the broader aspects of well-being - physical, mental, and emotional. I feel that everyone can benefit from improved nutrition, whether it’s for improved performance or overall well-being.

I began my journey in the fitness industry in 2015 with the intention of helping people work to their goals with efficiency and minimal injury risk. Having fallen in love with basketball as a young kid, I set out to become the best athlete I could, hoping to one day play sports professionally. Limited knowledge of how to train for sport and properly refuel and rest my body slowly wore me down physically, resulting in many ailments, movement compensations and lingering pain. Seeking remedy for my own issues, I gained inspiration to dedicate my learning more about the human body, proper training technique and nutrition, to better serve others towards achieving their desired results. I use these pillars to create fun, strategic and systematic training programs, while striving to always be a student who never feels their learning is complete.

I’m a Bay Area Native from Mill Valley. Growing up I spent my free time skateboarding, hiking, kayaking, body-surfing & swimming. I have always led an active healthy lifestyle and am constantly finding ways to challenge my body.
In my mid 20s I was struck with Celiac, this diagnosis forced me to adopt a disciplined diet (100% gluten free) and pushed me further into my fitness passion. Fortunately, it led me deeper into understanding the mind-body connection and enhanced my fitness lifestyle. This situation changed my perspective on work-life balance and wellbeing. I wanted a career that focused on health & wellness which led me to become a Certified Personal Trainer.
I have worked with many different clients, from de-conditioned working professionals, to retired athletes, to aging adults. My fitness beliefs revolve around having body awareness, understanding the dynamic between exercise, nutrition, and using movement as medicine. I structure my training to safely & effectively help my clients become strong. My goal is to help you boost your confidence, build and maintain strength and create a balanced lifestyle with a training program you will stick to consistently and also enjoy. I want you to look good and feel good! Outside of work I love to cook, bake, travel, explore the outdoors, and listen to music from classic rock to blues to hip hop and reggae. Getting a cup of chai tea or matcha is a daily ritual of mine.

My passion for fitness started at a young age playing a variety of sports growing up in the Bay Area. I was never really talented but what I lacked in skill I made up for in effort. I knew I had to bridge the gap. After going through phases training for strength with Powerlifting, being more fit with Crossfit style workouts, then focusing on power through Olympic Weightlifting, I realized that what it really comes down to is fitness for longevity.
I attended Cal State East Bay for both my Bachelors and Masters Degrees in Kinesiology where I focused on a broad range of topics including Physiology, Biomechanics, and Exercise Psychology. The knowledge I’ve amassed through school and 10 years of experience has helped me train individuals with a variety of goals whether they’re looking to lose weight, build muscle, or improve their overall health.
My training philosophy is all about building a strong foundation and instilling good habits. I am a firm believer that to live a long healthy life, exercise is the backbone, while moving often and well are requirements in creating long lasting results. Training with me is more than exercise and burning calories. It is a systematic process that starts with seeing how you move and creating a plan from there. I understand that everyone's fitness journey is different, so I tailor my training programs to each individual client's needs, goals, and lifestyle. I also focus on creating a supportive and encouraging environment where my clients feel comfortable pushing themselves.

My approach as a trainer is to build confidence and create lasting habits to help improve one's overall quality of life. I emphasize strength training modalities that can be transferred from the gym to daily life. I believe everything a person does inside the gym makes everything they do outside the gym better. My programs are structured to have clients progressively build toward their ultimate goal. Everybody is different therefore every body is different, so training programs are catered to my client’s individual needs. My ideal client is anyone with a goal, a positive attitude, and a willingness to work hard.
\My love for fitness started when I was in high school competing in sports such as football and basketball. It was during this time that I learned the importance of exercise and proper nutrition. I became aware of how it had an impact on my overall health and wellness. I attended Central Michigan University to earn my bachelors degree in Exercise Science. From there I developed my passion to help other people obtain their highest quality of life via fitness.
I have over 16 years of experience as a trainer. From training individual clients to large groups, I’m also experienced with sports performance training and working in physical therapy clinics. My career has led me to take on several management positions in corporate fitness clubs. I’ve coached and mentored other trainers, helping them to develop skills and build successful businesses. This wide array of experiences has helped to build a foundation of knowledge, communication skills, and confidence to be able to help anyone achieve any goal they wish to attain.

"Become what you've always wanted to be". That's the quote that I live by to this day. Being a Mexican native and a daughter of two immigrant parents, fitness was never a priority. Yes, I grew up playing sports such as soccer and track, but school was always number one. When I came out to San Francisco in 2016 to pursue my dream as an artist, I realized it was going to be much harder than I thought. I developed a lot of stress because of school and found my outlet in the gym. I started my journey not knowing much but stayed committed. I went in every day even after 8-12 hour painting sessions to let my body move and react in ways it never did before. Starting at just 100 lbs, I changed my eating habits, became more aware of my body's needs, and actually listened to those signs and gained 30 lbs in the process. I have become who I wanted to be, feeling strong, understanding movement patterns and now I can help others.
My goal as a personal trainer and fitness advocate is to help others move well, move pain-free, and move freely. I program with needs and wants in mind and believe that building strength and mobility is the key to pain-free moving. Whether you are looking to gain or lose weight, increase flexibility and mobility, body build, work on endurance or simply want to move well, I know we can work on those things together and get you to where you want to be and then some.

I’ve always been active but even as a three-season athlete in high school, I struggled with my weight, weighing over 200lbs. This was because I didn’t know how to properly care for my body. It wasn’t until I learned how to push myself and find joy in the process that everything changed. Now, I’m excited to help my clients find the same confidence and joy in their fitness journeys, no matter where they start.
As a personal trainer and run coach with a background in Psychology from the University of Oregon, I take a holistic approach to training that considers both your internal mindset and the external factors that shape your fitness journey. This comprehensive perspective allows me to create customized programs that build not only physical strength, but also mental resilience, motivation, and emotional well-being.
My mission is to empower my clients inside and outside the gym. Training with me isn’t limited to in-gym personal training sessions; my clients have the opportunity to join me at my run club, stretch class, or get personalized run coaching. All of these components work together to support everyone's fitness journey. Whether you're looking to lift heavier, increase your VO2 max, move better, or simply stay healthy, I’m here to guide you every step of the way. Together, we’ll create a training experience that fosters a lasting love for fitness and helps you reach your full potential.

I started my fitness journey like many other 15 year old kids growing up in San Diego - I signed up for the local gym to get some muscle for the beach! What I didn’t realize when I walked through the doors that day was that I had found something that would ignite a lifelong passion. In 2008 I moved to the bay area to attend Sonoma State University where I would go on to get my bachelors degree in Kinesiology to begin a lifelong pursuit of health, fitness and movement.
In my 10 years as a trainer I have a diverse background of experiences: training in gyms, running large and small groups (indoors and out), rehab clinics, athletic training development, corporate fitness and kettlebell specialization. This wide array of experiences has helped to build a foundation of knowledge and confidence to be able to help anyone achieve any goal they wish to attain
My approach as a trainer is to teach movement, and fundamentally change behaviors. I don’t believe in a one size fits all approach - there are many different paths that lead to success and I am committed to finding the one that will best suit your lifestyle while leading to your goals, so that we can make changes that will last long term. Whatever the path we take, we’ll be sure to improve strength, correct movement patterns and postures, and have fun along the way!
I take a data-driven approach, through testing and tracking, as a way of constant feedback so that we can make sure you are maximizing the results from your hard work. My ultimate driver is to teach and instill a lifelong movement practice with everyone I work with.

Hi there!. Let me share a bit about myself. Growing up, I was that shy, skinny kid who always hung back in the crowd. But about ten years ago, I decided it was time for a change and started my fitness journey. Little did I know, this journey would light a fire in me, boosting my confidence and transforming how I approached life and people.
Before diving into personal training, I was a swim instructor through high school and college. I loved every minute of it! There's nothing quite like watching someone progress and knowing you played a part in their journey. After looking back, that's when I realized how much I enjoyed teaching and supporting others.
As your personal trainer, my mission is to help you achieve the physical and mental transformation you've always envisioned for yourself. While my main focus as a trainer is body recomposition, I firmly believe that creating a surrounding where we enjoy the process is going to produce the longest lasting results. Whether your goal is to gain muscle and become stronger, lose weight, or just to improve your overall health, we’ll work together to create catered workouts along with sustainable lifestyle changes to ensure we're in a safe, efficient, and most importantly, fun environment.
When I'm not in the gym, you can find me learning a new language or enjoying some downtime with video games.
Let's get started on this exciting journey together. I can't wait to see what we can achieve!

My journey in fitness began at the age of 14 when I enrolled in a weight training class. My instructor was a former trainer to olympic athletes, and he preached the importance of living a healthy life. I was fascinated by human anatomy and how the muscles in our bodies work together to help us move. I was inspired to learn more about ways that we can develop healthy habits to improve quality of life, and in the process of that I found purpose in spreading this knowledge to people looking to progress their health.
As someone passionate about mental & physical well-being, I aim to uplift those I work with who are on a journey to self improvement - whether they are new to the world of fitness, or have years of experience. Each person has their own definition of what physical fitness means to them, and it means a lot to me to be able to help in achieving that goal.
I specialize in strength training that utilizes machines, free-weights, and calisthenic exercises. I believe that proper form is at the foundation of all exercise, allowing for the safe and efficient progression of your physical fitness.
Outside of training I love cycling, finding new recipes to cook, practicing martial arts, playing guitar and exploring music genres.

At a young age I was active but didn’t have a healthy eating habit. I would stuff myself with junk food and tons of sugar. Then I got introduced to wrestling and Brazilian jiu-jitsu, doing these sports taught me the importance of eating healthy and how impact our performance.
Doing marital arts taught me self discipline and how to take care of myself to perform the best I can. Fast forward, after high school I continued on to become a trainer for 7 years. The feeling of helping someone overcome obstacles in their life through fitness has been so rewarding to me. I never knew fitness could have such a big impact in our lives until I heard clients telling me their relationships have gotten better, they are more clear minded throughout the day and they feel their confidence coming back.
I am passionate about helping my client get the results they need through strength and conditioning training and building a strong foundation.

Through an in-depth fitness assessment designed to understand your unique needs, I create a completely customized training plan tailored to you.

My fitness journey began when I was preparing for Navy Dive School. I became fascinated by the mental and physical resilience people can develop when striving to reach a goal. My fitness goals started small, celebrating the little wins along the way, and eventually grew to include long-distance triathlon races. After my military service, I discovered a passion for helping clients achieve their fitness goals but took a detour to become a financial advisor.
While I was sharpening my skills in goal-setting and strategic planning, I also came to understand the firsthand impact of being desk-bound all day. Grappling with long work hours, a sedentary lifestyle, and the mental strain they carried, I once again embraced my true calling: empowering individuals to enhance their physical well-being by guiding them through the complex fitness world, with expertise, kindness, motivation, and unwavering support. As a dedicated student of life, my drive for knowledge is never-ending. I explore diverse schools of thought which allow me to offer my clients workouts rooted in the latest results-driven research and real-world application.
I aspire to create a training environment that fosters growth by establishing a strong connection between the mind and muscles through intentional movements. We live in a world that is constantly on the move and there will inevitably be days when sleep or nutrition fall short. During those moments, I am here to offer even greater support, adapting and making the changes needed to keep you feeling your best.
I specialize in creating tailored training programs, functional strength and conditioning, mobility and stability enhancement, balanced muscle growth, effective weight loss, as well as flexibility and mobility for desk-bound professionals.
During my down time, you’ll find me immersed in ocean dives, trekking alongside my rescue pup on hiking adventures, or cruising on a long motorcycle ride. My constant pursuit is to discover life’s balance, one mindful movement at a time.

My passion for fitness and strength training started as a teenager growing up in Providence, Rhode Island. Driven by my desire to become the best version of myself, bodybuilding has allowed me to develop strength and confidence both inside and outside of the gym. With over a decade of experience lifting weights and exercising, sustaining fitness has never been more important to me for living a longer and healthier life.
My goal as a fitness trainer is to make fitness fun and enjoyable by working alongside my clients on building up their bodies all while laughing along the way. I look at where my clients currently are with their strength, cardio, mobility, and movement patterns and build my fitness programs accordingly. I bring a holistic bodybuilder’s approach to general fitness meaning a high focus on solid form, building a deep mind-to-muscle connection, and a focus on quality movement. Whether your goal is to lose weight, put on muscle, overcome an injury, or just feel overall better in your everyday life, I am the trainer for you.

Born and raised in San Francisco, growing up being the “runt” of the group I was seeking purpose and courage. Involving myself with fitness at the age of 14 has been one of the most life changing and rewarding challenges I’ve experienced. Till this day, I’ve made it a passion to continue the life long journey to becoming a better version of myself. Everyday that I’m active is another day I get to learn more about myself and what I’m capable of. Fitness has given me confidence to physically and mentally project myself in a positive light.
I have a profound passion for Martial Arts. During my freshman year of high school, I started wrestling and strength training and fell in love with both. This has lead me to explore other disciplines throughout my life. I am now participating in sports such as boxing and currently still strength training and actively practicing Muay Thai (Thai style boxing).
I have made a commitment to improve the wellbeing of others by providing functional strength training while also, incorporating traditional muay thai or boxing fundamentals to keep it fun and exciting. I am a firm believer in building your body to have longevity and durability.

I was Born in Chicago although I spent the majority of my life in Northern California. My path to this field stems from my experience as a collegiate athlete. Playing Soccer in college allowed me to experience a wide array of injuries which halted my ability to pursue my life long passion. However my passion for the understanding of the human body and movement came into fruition in my last couple years of college. Knowledge in this field allows me to continue exploring physical challenges myself as well as help others explore their bodies potential.
I believe in a holistic approach to health and fitness by incorporating healthy rest and a well balanced diet being just as crucial as our time spent in the gym. In the gym I like to focus on functional movements with an emphasis on building a solid foundation that will allow you to achieve any physical goals you have while minimizing injury. I believe physical, mental and spiritual growth starts and ends with your health. Designing the right program based on your fitness level can allow us to achieve any goals you set forward while providing your body with the love and care it deserves.

Born and raised in Fairfield, California. Fitness has always been involved in my life in some way. Growing up I played soccer for about 10 years before I found that my real passion was in the weight room. Being strong is always something that has been important to me, so when I found strength sports, I began to thrive. Starting to compete in strongman and powerlifting is what drove me to getting my certifications. I found that by helping people get stronger and bring up their weak points, it had a lot of carry over into their everyday life. Outside of competing, my true passion is helping people, and the best way I have found to do that is by building confidence through exercise. The other thing I love about being in this industry is helping people work on imbalances and get them out of pain. I like to execute a mixture of methods to achieve the desired result and I’ve found that in doing so it helps keep the gym interesting.
Outside of the gym I love to read, listen to music, and spend quality time with my family.

Growing up, I overlooked health and exercise often. I was out of shape, overweight, and lacked any sort of drive and self confidence. Everything changed when I got my first gym membership in High School.
I fell in love with weight training, got into good shape, gained confidence, and found a direction to lead my life. Since then, I have continued to train, got my degree in Exercise Science, and became a certified Personal trainer.
Now I aim to use everything I've learned about exercise to help my clients in their own fitness journeys. I believe a healthy lifestyle has so many benefits to offer both physically and mentally and I think everyone should give it a try.
My goal as a trainer is to make exercise fun and enjoyable for my clients while also helping them reach their goals. If you're looking to get stronger, build muscle, lose weight, or just get active, I believe I can help.

Born and raised in SF in a Hispanic household. I was overweight and was never happy with myself. I didn’t like looking at myself in the mirror and nobody in my family was into fitness. I decided to get into fitness myself and even though I managed to lose 67 lbs. I made so many mistakes and injured myself by overtraining throughout the process.
I realized how important investing in your own health can be. Fitness became a passion and I want to help others to not make the same mistakes I did when I started. I changed my major in school to study to become a PT and got into nutrition to level up my training. The more I learned the more I knew I could help more people.
My goal as a personal trainer is to make fitness fun and to help people achieve their goals in a safe manner with proper training . I work on strength and mobility to make sure everyone can move throughout their days without any pain or discomfort.
Whether your goal is to lose/gain weight, work on mobility, endurance, to train with an injury, or just to feel better over all, I will be there to support and guide you.

I grew up playing sports, but it wasn't until after high school that I began to form a real understanding of strength and athletic training. Before I became a personal trainer, I trained and participated in combat sports (primarily submission grappling but also kickboxing and MMA) as both a competitor and a coach. My training philosophy is that strength is the key which unlocks everything else, whatever one's goals may be.
