Ankle dorsiflexion work
Restore the ankle bend that governs squat depth, gait mechanics, and knee tracking.
Why it works
Ankle dorsiflexion — how far the shin travels over the foot — is often the primary structural limiter in squatting and lunging. When insufficient, the heel rises or the knee caves as compensations, loading the knee and hip in unfavorable positions. Increasing dorsiflexion range removes the bottleneck, improving mechanics throughout the chain.
How to do it
- Stand facing a wall with one foot close to the base. Drive the knee forward over the little toe without lifting the heel.
- Find the exact distance from the wall where the heel just begins to rise — that is your current range.
- Do 10 slow repetitions touching the wall, working for small range improvements over weeks.
- Add a calf stretch and tibialis raises to address both the posterior and anterior chain.
Evidence
Limited dorsiflexion is consistently identified as a risk factor for knee injury and a limiter of squat mechanics in sports science and physical therapy research. (observational)
Most evidence is observational or cross-sectional; interventional trials showing that increasing dorsiflexion reduces injury are less numerous.

Common mistake
Only stretching the calf statically and ignoring the anterior ankle capsule restriction, which is often the true structural limiter — and does not respond to calf stretching.

More practices for Mobility Training, Made Practical
- Controlled Articular Rotations (CARs)
Slowly rotate each joint through its maximum range every day to maintain and map that range.
- Convert passive flexibility into active range (PAILs and RAILs)
After reaching end range passively, isometrically contract against the stretch to teach your nervous system to own it.
- Hip 90/90 position
Sit with both knees at 90 degrees to simultaneously work internal and external hip rotation.
- Thoracic spine rotation
Unlock the mid-back rotation that your shoulders, neck, and lower back depend on.
- End-range loading (strength through full range)
Train muscles at end range of motion so new flexibility becomes strength, not vulnerability.
- Daily floor sitting
Replace some chair time with floor positions to maintain hip and spine mobility without extra gym sessions.
- Overhead shoulder preparation
Restore the thoracic extension and scapular mechanics that safe overhead movement requires.
