The Core Three

Trade the guesswork for measurement you can act on.

DEXA body composition, VO₂ Max, and RMR, run back to back in a single South Bay visit, so you leave Redondo Beach holding the full picture instead of another estimate.

Body Composition

The scale hands you one number. A DEXA scan shows what that number is made of.

A DEXA scan runs a low-dose X-ray the length of your body and splits your weight into fat, lean muscle, and bone density, read region by region instead of one lump sum. This is the same measurement hospitals and research labs treat as the reference standard, and the scan itself is over in under 8 minutes. You walk out knowing which regions carry your muscle, where fat sits, and the one area worth working on first.

>10%
How far a smart scale can drift from your real body fat. A DEXA scan stays near ±2%, the reading treated as the clinical gold standard for body composition.

VO₂ Max Test

Few numbers predict how long you live as clearly as this one.

VO₂ Max measures how efficiently your body pulls in oxygen and turns it into effort as the pace climbs. Whether you run The Strand along the coast or just want to reach the top of the stairs with breath to spare, it reflects far more than fitness. As a longevity marker it outweighs smoking, blood pressure, or cholesterol. You breathe through a mask, push through a graded treadmill effort, and we read your true ceiling. From there, the number turns into a plan to raise it.

The least-fit group carried close to 5 times the death rate of the fittest, across 122,007 people studied (Mandsager et al., JAMA 2018).

Resting Metabolic Rate

Most calorie targets are a guess your body never signed off on.

An RMR test shows how many calories you burn at complete rest, the real floor every meal plan should sit on. The online calculators most people trust can be off by 20 to 30%, and that gap is often why fat loss stalls and carefully tracked macros lead nowhere. Fifteen quiet minutes breathing into a mask return a number drawn from your own metabolism instead of a population average.

±20%
A common gap between a calculated metabolic rate and a measured one. That margin can undo a nutrition plan long before the scale gives any hint why.
