Static Wall Sit
The Static Wall Sit is a bodyweight isometric exercise that targets the quadriceps, glutes, and core by holding a seated position against a wall. It builds lower body endurance and joint stability without the impact of dynamic movement.
Iridium tracks this isometric hold by correlating duration and RPE with your current body weight to measure progressive overload accurately. This time-under-tension contributes directly to your weekly Quad volume landmarks, ensuring the intensity stays within your calculated Maximum Recoverable Volume.
Form Cues
- Slide down until your thighs are parallel to the floor
- Press your entire back flat against the wall
- Position your knees directly over your ankles
- Drive your heels firmly into the ground
- Keep your chest up and core braced
- Don't let your knees cave inward toward each other
- Don't place your hands on your thighs for support
- Don't arch your lower back off the wall
- Don't let your knees slide forward past your toes
- Don't hold your breath
Common Mistakes
- Resting hands on knees to reduce load
- Not sitting deep enough (hips above knees)
- Rounding the lower back
- Allowing knees to collapse inward
- Holding breath during the exertion
Muscles Worked
The primary focus is on the quadriceps, which must maintain constant tension to keep your body suspended against gravity. Secondary engagement occurs in the glutes and hamstrings to stabilize the hip joint, while the core muscles work isometrically to keep your back flat against the wall.
