This is sick! I lift and I've been wanting something like this for a looong time. I think the end game of this technology can help people without a coach learn to lift. From what I've read about how people learn, immediate feedback is extremely important, as in within a couple of seconds. I'd love it if this took bar path and velocity information, and put it into a machine learning system. The app could watch you in real time and immediately tell you whether it was a good lift or what was wrong with it. Lift your butt up faster, or lift the bar faster, slower or whatever. I think you'd need to sit down with a couple good coaches and have them classify what's wrong or right with several hundred lifts to get your training dataset—but I would love to pay for this product.
