Hey HN! Finally crossed off a nagging side project idea - using AI/ML to give realtime feedback on gym form (can be extended to any hobby where technique matters).

I used posenet to capture coordinates in real-time, and GPT with some few-shot prompting to give feedback. Curious what ideas folks have for different/better approaches here!

Looking for collaborators if anyone wants to hack on this together

Cheers! + super appreicate any thoughts/feedback

How do you like posenet? I used it a few years back when they first launched and found the accuracy lacking. I built a basketball shooting feedback app and it consistently made wrong keypoint predictions at critical times. Curious how you measure this in the wild as well.
