How to Do It

1Stand with your back against a wall
2Walk your feet out about 2 feet from the wall
3Slide down the wall until thighs are parallel to the floor
4Your knees should be at 90 degrees, directly above your ankles
5Keep your back flat against the wall
6Hold this position, breathing normally
7Start with 20-30 seconds and build up over time

How Many Calories Do Wall Sits Burn?

Wall sits are an isometric exercise — calorie burn is lower than dynamic movements but still meaningful, especially when held for longer durations or performed in multiple sets. Use our free Calories Burned Calculator to find your specific number.

Common Mistakes to Avoid

Knees extending past toes - move feet farther from wall

Not going low enough - thighs should be parallel

Holding your breath - keep breathing steadily

Letting hips sag or rise - maintain static position

Make It Easier

Higher wall sit (less knee bend)
Shorter hold time
Feet closer to wall

Make It Harder

Single-leg wall sit
Wall sit with calf raises
Longer hold times (60+ seconds)

Why the Wall Sit Is More Valuable Than It Looks

The wall sit is one of the most underrated exercises in existence. It looks passive — you're just sitting against a wall — but the quadriceps are sustaining a continuous isometric contraction throughout the entire hold. There's no rest at the top, no momentum to coast on, no way to cheat the movement. Your muscles are under constant tension from start to finish. This makes wall sits uniquely effective for building the type of muscular endurance that transfers directly to real life — climbing stairs, getting up from chairs, hiking, skiing, and any activity that demands sustained leg strength. Research shows that isometric training also has a measurable blood pressure-lowering effect, making it one of the few exercises with both musculoskeletal and cardiovascular benefits simultaneously. For anyone who sits at a desk all day, a 60-second wall sit is one of the fastest ways to re-engage the quads and glutes that prolonged sitting systematically deactivates.

Wall Sits After 40 — Joint-Friendly Leg Training

After 40, joint health becomes an increasingly important factor in exercise selection. Wall sits are exceptionally joint-friendly because there's no impact, no rapid direction changes, and no movement through the knee joint — the angle stays fixed throughout. This means the knee cartilage isn't subjected to repetitive compression-decompression cycles the way it is during squats, lunges, or running. For adults with mild knee sensitivity or early-stage osteoarthritis, wall sits often remain comfortable when dynamic leg exercises become problematic. They also strengthen the VMO — the inner quad muscle that stabilizes the kneecap — which is frequently weak in people with knee pain. Physical therapists regularly prescribe wall sits as part of knee rehabilitation programs for exactly this reason. Start with a higher position (less than 90 degrees) if full depth causes discomfort, and progress the depth gradually as your quad strength improves.

Frequently Asked Questions

How long should you hold a Wall Sit?

Start with 20–30 seconds for 3 sets. Most beginners hit muscular fatigue around 30–45 seconds. Intermediate practitioners should aim for 45–60 seconds per set. Beyond 90 seconds, you're training endurance more than strength — at that point, progress to single-leg wall sits or add weight on your lap instead of extending time.

What muscles do Wall Sits work?

Wall sits primarily target the quadriceps (front of the thigh), which sustain an isometric contraction throughout the hold. Secondary muscles include the glutes, which help stabilize the hip angle, the calves which maintain ankle position, and the core which keeps your torso upright against the wall. The hamstrings are also engaged as stabilizers.

Are Wall Sits bad for your knees?

For most people, wall sits are knee-friendly because there's no impact and no movement through the joint — the knee angle stays fixed. If you have existing knee pain, position your feet farther from the wall so your knees stay behind your toes and use a higher seat position (less than 90 degrees). If pain persists at any angle, stop and consult a healthcare professional.

Do Wall Sits build muscle or just endurance?

Wall sits primarily build muscular endurance and isometric strength rather than muscle size. Isometric exercises like wall sits strengthen the muscle at the specific angle held. For muscle growth (hypertrophy), you need exercises with movement through a range of motion — squats, lunges, and step-ups are better for building leg size. Wall sits are excellent as a complement to those exercises.

Can you do Wall Sits every day?

Yes — wall sits are low-impact and don't cause significant muscle damage, making daily practice safe for most people. They're particularly effective as a daily addition to a desk-bound routine because they activate the quads and glutes after prolonged sitting. However, if you're doing them to muscle failure, allow 24–48 hours between sessions.

Are Wall Sits good for runners?

Yes — wall sits build quad endurance and knee stability, both of which are critical for running performance and injury prevention. They strengthen the VMO (vastus medialis oblique), the inner quad muscle that stabilizes the kneecap during running. Many running coaches recommend wall sits as part of injury prevention routines, particularly for runner's knee.
