The problem

A test I set myself. How much app fits into one single file, with nothing to install and no server?

What I built

One 76 KB file that opens with a double click.

    An 8-week training plan. Every exercise shows which muscles it works, drawn by a small program I wrote.

    Animated stick figures show how each exercise is done.

  • check_circle

    Step-by-step coaching, a tracker for your sets with charts, and a paper log you can print.
