There a home gym setup called Tempo that claims to do this. I have the scaled down mobile app version so idk if the full setup is more informative, but it doesn't really give a lot of feedback at all. It basically just tracks the movement of the dumbbell plates that they send you to count your reps, and if you aren't moving the weight to the correct position your rep won't count. It definitely doesn't do anything like correct your form based on your body position like "hey straighten your back" or anything
