Wall sit

How to do it

1. Stand with your back against a wall, then walk your feet out about two foot-lengths, hip-width apart.
2. Slide down the wall until your thighs are parallel to the floor.
3. Adjust your feet so your knees sit directly over your ankles.
4. Hold with your back flat against the wall, breathing steadily.

Form tips

• Press your whole back and head lightly into the wall.
• Rest your arms at your sides instead of pushing on your thighs.
• If it is too hard, slide a little higher and hold there.
