Wall Sit
How to Do a Wall Sit
Stand with your back against a stable wall and your feet around hip- to shoulder-width apart.
Walk the feet forward enough that you can slide down the wall without the knees feeling crowded.
Brace your trunk and slowly slide the back down the wall while bending the knees and hips.
Choose a depth you can hold comfortably. A 90-degree knee angle is a common advanced target, but beginners can stay higher.
Keep the knees tracking with the toes and distribute pressure through the whole foot.
Keep the back supported by the wall and hold for the planned duration while breathing steadily.
Finish by sliding back up or stepping out carefully rather than collapsing at the end.
Form Check & Technique
DO THIS (Technique Tips)
- Start higher and progress deeper gradually.
- Keep the knees tracking with the toes.
- Press through the heels and midfoot.
- Keep hands off the thighs.
- Breathe steadily throughout the hold.
- Add time before adding heavy load.
AVOID THIS (Common Mistakes)
- Going Straight to a 90-Degree Hold — Fix: start higher if you cannot maintain the position comfortably.
- Knees Collapsing Inward — Fix: keep the knees tracking with the toes.
- Feet Too Close to the Wall — Fix: walk the feet forward enough that the heels stay down.
- Pushing on the Thighs — Fix: keep the hands off the legs.
- Holding the Breath — Fix: keep steady breathing while maintaining the brace.
- Staying Until Form Completely Breaks — Fix: end the set while you can still exit under control.
About Wall Sit
The wall sit, also called a wall squat, is an isometric exercise in which you hold a squat-like position with your back supported by a wall. It primarily challenges the quadriceps while the glutes, calves, hamstrings, and core help maintain the position. The exercise is easy to scale by changing the depth, hold duration, load, or number of working legs.
Wall Sit Muscles Worked
The quadriceps produce continuous isometric force to hold the knee angle while the glutes and hamstrings help stabilize the hips.
- The calves contribute to lower-leg stability, and the core helps keep the torso controlled against the wall.
Sets & Reps Guidance
Technique / Learning
Technique: 2–3 holds of 15–30 seconds at a higher, comfortable position.
Strength Focus
Loaded isometric strength: 3–4 holds of 20–45 seconds with a light-to-moderate load after bodyweight holds are stable.
Muscle Growth (Hypertrophy)
Muscle endurance / accessory work: 3–5 holds of 30–60 seconds at a challenging but repeatable depth.

How Deep Should a Wall Sit Be?
A thigh-parallel position with roughly 90 degrees of knee bend is a common target, but it is not required. A higher position reduces difficulty and can be better for beginners.
How Long Should You Hold a Wall Sit?
Twenty to sixty seconds is a practical range for many people. Start with a duration you can hold with steady breathing and good knee position, then add a few seconds at a time.
Why Wall Sits Feel So Hard
The quadriceps stay under continuous tension instead of receiving the brief changes in muscle length that occur during normal squat repetitions. That uninterrupted isometric demand creates a strong local burn.
How to Progress Wall Sits
Progress by holding longer, moving slightly deeper, adding a light load across the lap, or performing a single-leg variation. Change one variable at a time.
Wall Sit vs Bodyweight Squat
A wall sit is isometric: the joint angles remain mostly fixed.
- A bodyweight squat moves through repeated knee and hip flexion and extension.
- Wall sits are useful for isometric endurance but do not replace dynamic squat strength.
Are Wall Sits Knee-Friendly?
Many people find wall sits easier to control because the wall supports the torso and the knees stay at a fixed angle. If a particular angle causes pain, use a higher position, shorter hold, or another exercise.
