If you’re serious about your health, you need more than a scale or a smartwatch.

DEXA scans and VO2 Max testing are considered the gold standard for understanding body composition and cardiovascular fitness.

What is a DEXA Scan?

DEXA (Dual-Energy X-ray Absorptiometry) measures:

  • Body fat percentage
  • Lean muscle mass
  • Bone density
  • Regional body composition

Unlike traditional methods, DEXA provides highly accurate, segmental data.

Why DEXA Matters

With a DEXA scan, you can:

  • Track fat loss vs. muscle gain
  • Identify imbalances in your body
  • Monitor bone health over time
  • Measure real progress—not just weight

This is especially important for athletes and individuals focused on body recomposition.

What is VO2 Max Testing?

VO2 Max measures your body’s ability to use oxygen during exercise.

It is one of the strongest indicators of:

  • Cardiovascular fitness
  • Endurance performance
  • Longevity and overall health

Why VO2 Max is a Key Metric

Higher VO2 Max levels are associated with:

  • Lower risk of cardiovascular disease
  • Improved endurance and recovery
  • Better metabolic efficiency

It’s not just for athletes—it’s for anyone who wants to understand their fitness at a deeper level.

Why You Should Combine Both

DEXA and VO2 Max together provide a complete picture:

  • Body composition (what your body is made of)
  • Performance capacity (how your body performs)

This combination allows for precise, individualized programming.
