Lunge Form Guide: Fix Front Knee Tracking and Build Better Control

Improve lunge form with better front knee tracking, stronger torso control, cleaner depth, and more repeatable reps from set to set.

Quick answer

Romanian Deadlift Form Guide: Better Hinge Depth Without Losing Position

A Romanian deadlift form guide for cleaner hinge depth, better torso control, stronger hamstring loading, and better AI form analysis results.

Short answer: A good Romanian deadlift is a controlled hip hinge with clear hamstring loading, a bar path that stays close to the legs, and a torso position that changes because of the hinge, not because you lose tension.

Squat Form Guide: Depth, Knee Tracking, and Torso Control

A practical squat form guide covering depth, knee tracking, torso control, camera angle, and how to fix the most common squat faults.

Short answer: A strong squat usually comes down to three things: consistent depth, knees tracking over the mid-foot, and a torso angle that stays controlled throughout the rep. Most squat problems show up when one of those breaks down under fatigue.

What an AI Form Score Actually Means

Learn how to read an AI form score, what primary faults mean, and how to turn coaching cues into better lifting technique from session to session.

Short answer: A form score is a summary of movement quality signals like range of motion, tracking, torso control, symmetry, and fault frequency. The most important output is usually the primary fault and next correction, not the exact number by itself.
