yo-WASSUP/Good-GYM ? reverse-engineered prompt

Build me a desktop fitness assistant app that uses my webcam to watch my form, count reps automatically, and give me simple real time feedback while I work out.

I want it to recognize common exercises like squats, push ups, sit ups, and dumbbell movements, then show a live skeleton view, angle measurements, rep counts, and workout stats in a clean interface. It should run locally on my computer for privacy, work well on CPU by default, and only use GPU acceleration if it’s available. Please make the exercise types easy to edit from a simple data file, so I can add new movements without changing code.

Also include a history or progress screen, settings for goal tracking, and a way to switch between the detection view and stats view without crashes. If anything is unclear, check the current docs online first.
