(01) How it’s done
On the day
From the DEXA scan, split into arms, legs and trunk, and adjusted for your height.
We also compare left and right, which shows imbalances after an injury.
(02) Why it matters
What it tells us
Muscle is the organ of longevity. It soaks up blood sugar, protects your bones and keeps you independent later in life.
Most adults lose muscle every decade after forty unless they train for it. This number tells us how hard to push.
(03) Same system
Body & strength
Measured on the same day, read by the same physician.
