I built a personal strength training monitor for myself. It's for anyone who lifts and wants to see where their training volume goes and how their strength changes over time without tracking it by hand. All the project files live on my laptop.

How I use it:

1. After every lifting session, I open AI in the terminal.
2. I log the exercises, weights, and reps in plain text.
3. It automatically builds the updated muscle heatmap for the week. Muscles hit with more sets appear redder, on a color-graded range.
4. It calculates a 1 rep max progression chart for each exercise over time, so I can see my progress.
5. The live heatmap shows which muscle or muscle group has been least targeted this week.

What it produces: a full-body weekly heatmap, a 1RM progression chart for each exercise, and a quick view of which muscles I've neglected that week.
