Bodyweight
The wall sit is an isometric exercise where you hold a seated position against a wall. It builds quad endurance and mental toughness. Hold for time with your thighs parallel to the floor.
How to Do Wall Sit
- Press your entire back flat against the wall and slide down until thighs are parallel to the floor
- Position your knees directly above your ankles at a 90-degree angle
- Keep your arms at your sides or crossed over your chest — don't push on your thighs
- Breathe steadily and focus on keeping your thighs parallel — don't creep upward as fatigue sets in

Common Mistakes to Avoid
- Not sitting deep enough — your thighs should be parallel to the floor, not at 45 degrees
- Placing hands on thighs for support, which dramatically reduces the quad work
- Letting your knees drift forward past your toes instead of keeping a 90-degree angle

Frequently Asked Questions
What muscles does the wall sit work?
The wall sit primarily targets the quadriceps through isometric contraction, with secondary engagement from the gluteus maximus, calves, and core.
How long should I hold a wall sit?
Beginners should aim for 20-30 seconds, intermediates 45-60 seconds, and advanced athletes 90+ seconds. If you can hold longer than 2 minutes, you're likely sitting too high — sink lower.
Wall sit vs squat — which is better?
Squats are far superior for building strength and muscle through dynamic movement, while wall sits build isometric endurance and mental toughness. Use wall sits as a finisher or when you don't have equipment.
