Setup
- Stand with your back against a flat wall and your feet about shoulder-width apart.
- Step your feet forward approximately 18 to 24 inches away from the wall.
- Ensure your feet are flat on the ground with toes pointing slightly outward or straight ahead.
How to do it
- Slowly slide your back down the wall until your thighs are parallel to the floor, forming a 90-degree angle at the hips and knees.
- Press your entire back, including your lower back and shoulders, firmly against the wall.
- Hold this position for the prescribed duration while maintaining steady, deep breaths.
- To finish, push through your heels and slide back up the wall to a standing position.
Form checklist
- Keep knees directly above the ankles, not tracking past the toes.
- Maintain a 90-degree bend in the knees and hips.
- Keep the lower back pressed flat against the wall with no arching.
- Do not rest your hands or arms on your thighs.
- Distribute weight evenly across the heels and mid-foot.
Pro tips
- Focus on driving your heels into the floor to maximize glute and hamstring engagement.
- Actively squeeze your glutes and brace your core to protect the spine and increase stability.
Make it harder
- Lift one foot slightly off the ground to perform a single-leg wall sit, alternating sides.
- Hold a weight plate or dumbbell against your chest to increase the resistance on the lower body.
