Iso Wall Sit
How to Do It
Back flat against a wall, slide down until hips and knees are at ~90°, thighs parallel. Keep the feet flat and under the knees, back pressed to the wall, weight in the heels. Hold for the prescribed time, breathing steadily, then stand to finish.
Why It Works
A sustained isometric hold builds quad strength-endurance and tendon stiffness under constant tension, training the muscles to resist fatigue at a fixed joint angle while teaching tolerance of a low, loaded posture.
Hockey Transfer
Develops the quad endurance and low, knee-bent posture-tolerance needed to hold an athletic skating stance through a long shift; builds isometric leg strength that supports stride position late in shifts.
Coaching Cues
- "Thighs parallel, knees over ankles"
- "press the whole back into the wall"
- "breathe steadily"
Common Mistakes
Hips rising above knee height; knees drifting past the toes; holding the breath
Progression / Regression
DB on the lap or single-leg
shorter hold or higher knee angle
Primary Muscles
Energy System
Strength/neural (isometric)
