What FormCheck checks

5 things on every rep of a romanian deadlift: knee bend, upper back, hips back, bar path and depth. Green passed. Amber means look at this, not bad. Grey means the camera did not see the joint.

How to film it

Stand side-on. Whole body in frame, feet to head. Camera still, about hip height.

Where the numbers are weak

• The knee number runs high. The tracker places the knee dot in front of the real knee when the thigh is flat.
• The upper back check cannot see your lower back. It measures the line from ear to shoulder to hip.
• Big plates hide your feet. The tracker then guesses the ankle. Film from further back.
• The bar check uses your wrist. 0.3 shin lengths means the bar touched your legs.
