Wall Sit

How to do it

1. Stand with your back flat against a wall and walk your feet about two feet forward, hip-width apart.
2. Slide down the wall until your thighs are parallel to the floor and your knees are bent to roughly 90 degrees, with your knees stacked over your ankles.
3. Keep your back and shoulders pressed into the wall, your core braced, and your weight through your heels.
4. Hold this position for the desired amount of time, breathing steadily, then push through your heels to slide back up the wall.
