How to track body recomposition

By David Pintarič, maker of ProgressLens · Updated October 29, 2026

In a recomp you lose fat and gain muscle at the same time, so the scale is the least useful tool you have.

Short answer

Track recomposition with progress photos every one to two weeks, waist plus arm or chest measurements, strength in your main lifts and a weekly average weight. A working recomp shows a falling waist, stable or rising arm and chest measurements, and roughly flat weight.

Who it works best for

Beginners, people returning after a break, and people with more body fat to lose see recomposition most clearly. Experienced, lean lifters usually do better alternating focused bulks and cuts.

Setting it up in ProgressLens

Front, side and back weekly with the ghost overlay; waist weekly; arms and chest monthly. Compare at 8 weeks. The comparison shows the bodyweight change between the two dates, which in a recomp should be close to zero.

FAQ

Frequently asked questions

How long does body recomposition take?

Expect 8–12 weeks before matched photos show a clear difference.

Can women do body recomposition?

Yes. The same signals apply; watch for cycle-related water changes in weight and waist.
