Quantify the exact velocity of your descent. Our AI tracks the "break point" angle where your hamstrings lose eccentric control, providing a hard data point for strength gains.
Identify L/R imbalances before they become tears. Deviations > 10% trigger priority corrective protocols.
Built on sports science data proving a 51% reduction in HSI rates through structured Nordic protocols.
Longitudinal tracking of break-point angles across your competitive season.
The Nordic Hamstring Curl (NHE) is one of the most effective exercises for preventing hamstring strain injuries (HSI). Research shows it can reduce injury rates by up to 51%. Our analysis ensures you are performing them correctly and measuring your eccentric strength progress.
SpeedTrackr uses advanced computer vision (pose estimation) to track 33 key points on your body. It calculates your hip and knee angles, descent velocity, and failure point in real-time derived from a simple video upload.
No. While traditional Nordic testing requires expensive dynamometers (costing $1000+), SpeedTrackr requires only your smartphone camera and a partner (or anchor point) to hold your ankles.
While absolute force isn't measured without sensors, our 'Control Score' is based on descent velocity and break angle. Elite athletes can control the descent until their chest is near the floor. Beginners often 'break' early. Our tool tracks this control improvement.
