I have been building LiftSheet for a while, and the request that kept coming back was some version of "show me where my training is actually going." So I built a muscle heatmap.

What it does: it takes every set you have logged over the last 90 days and shades a body figure by volume per muscle. Red is the most trained, grey and yellow the least. You can flip the figure front to back, and switch between a male and a female figure, with a per muscle breakdown underneath.

It lives in a new Muscles tab in Progress, and there is a planned version for a program too, so you can see how a split will distribute before you run it.

Two other things shipped alongside it. A colour key: every muscle name in the app has a colour, and the key shows a body coloured to match, so a name always maps to a place on the body. And move-and-add-a-day: when you move an exercise to another program you can now create the day for it in the same step.

The heatmap and the colour key are free. No account, everything stays on device, no third party analytics.

I added a muscle heatmap to my workout tracker that shades a real body by the volume you have actually logged. Here is how it works.
