PureStrength: AI Form Coach for Squat, Bench & Deadlift

PureStrength turns your smartphone into a virtual strength coach. By simply uploading a video of your squat, bench press, or deadlift, the app's AI engine breaks down your lift frame by frame, examining bar path, velocity, range of motion, side shift, and pause time to pinpoint exactly where your technique breaks down. Rather than guessing whether your form is correct, lifters get objective, data-driven feedback that highlights issues like insufficient squat depth or dangerous spinal curvature during deadlifts before they turn into injuries. Beyond form correction, PureStrength doubles as a performance tracking and programming tool. It calculates your estimated 1 rep max and builds a velocity zone-based training program tailored to your current strength levels, helping you train with the right intensity for your goals. Whether you're chasing a new personal record, coaching clients remotely, or simply trying to lift safely at home, PureStrength brings professional-grade biomechanical analysis to anyone with a smartphone camera.

1. Record a video of yourself performing a squat, bench press, or deadlift. 2. Upload the video directly into the PureStrength app. 3. Let the AI analyze your lift, generating feedback on bar path, velocity, range of motion, side shift, pause time, squat depth, and spinal curvature. 4. Review your calculated 1 rep max and personalized velocity zone-based program. 5. Apply the feedback to your next session and re-upload to track improvement over time.
