AI Form Checker

Correct exercise form means maintaining proper body alignment, engaging the right muscles, and moving through the full range of motion. Signs of good form include controlled movement tempo, joints tracking naturally, and no compensatory movements. The fastest way to check is to record yourself and use Gymaholic’s AI form checker for instant, personalized feedback on your technique.

Proper workout form starts with a neutral spine, engaged core, and controlled tempo throughout each rep. You should breathe consistently and move through the full range of motion for every exercise. Good form prevents injury, targets the intended muscles, and maximizes your results over time.

Upload a video of your exercise and our AI analyzes your movement frame by frame. It evaluates your posture, coordination, tempo, alignment, symmetry, and range of motion, then provides an overall score with specific feedback on what you’re doing well and what to improve.

The AI form checker supports over 1,800 exercises from our exercise library, including squats, deadlifts, bench press, overhead press, rows, pull-ups, lunges, and many more.

Our AI is trained on thousands of exercise demonstrations and provides detailed feedback across six categories: overall form, control, range of motion, tempo, alignment, and symmetry. For best results, film from a side angle with your full body in frame and good lighting.
