The tests, in plain English
A DEXA scan measures bone, muscle and fat, including the fat around your organs. A VO2 max test measures your fitness, which is strongly linked to long-term health. Both are most useful repeated over time, so you can see whether your training is working.
Think of it like checking a car. DEXA looks at the frame: your bones and muscle. VO2 max tests the engine: how well your heart and lungs deliver oxygen.
