PureStrength

The app offers detailed form analysis for three main lifts: deadlift, squat, and bench press. For deadlifts, it detects shoulder positioning to avoid rounding, ensures proper hip movement and lat/core tightness, and checks lockout technique. For squats, it monitors depth for optimal muscle activation and alerts users to imbalances or alignment issues. For bench press, it provides feedback on bar path and control, and evaluates grip, elbow position, and body mechanics. The app also includes 3D analysis, which is turned on by default in the latest version.

FormCheck AI is suitable for any lifter looking to improve their form on compound movements. It can be used to prevent injuries by identifying improper technique, and to maximize results by ensuring optimal muscle activation. The app also allows users to track progress and celebrate milestones. Reviews from users highlight its usefulness in perfecting form and improving performance, with one reviewer noting they use it every time they perform compound movements.
