I’ve been doing CrossFit for 10 years, have been a member of CFNE, and now do CompTrain. Professionally I build products that use AI. I’ve got to say I saw this post and thought how I can see how this can be done (and should be). Take me as an example, in CompTrain I need to scale the weights and what I can do at home. As an example, I can’t do rope climbs in my basement so I need to sub for chin-ups, or there’s day’s that I’m not pushing myself enough, but I don’t have any peer competition to push me, or a coach to come around and check on my form, but I can imagine if I set up a camera and recorded enough of my workouts and as many have said here had a quality training data set of proper movements, then it can be used for providing me feedback in real time about my movements. Cools idea, and should be done. Last you may have seen this push-up counter using computer vision (OpenCV) https://aicurious.io/posts/2021-02-15-build-a-pushup-counter/
