Does a DEXA repeated every ten weeks give me an usable lean-mass trend?

Asked 2 Feb 2026Modified 6 months agoViewed 4.1k times

Scale weight, waist circumference and a repetition maximum, all logged weekly.

I suspect the honest answer is that it depends, in which case I would like to know on what.

Assume I can obtain either option without difficulty, so availability is not the deciding factor.

Under what conditions does the answer flip?
