Make sure your back is flat against the wall.
Place your feet firmly on the ground, shoulder-width apart, and then about 2 feet out from the wall.
Slide your back down the wall while keeping your core engaged and bending your legs until
they’re in a 90-degree angle—or right angle. Your knees should be directly above your ankles, not jutting out in front of them.
HOLD your position while contracting your ab muscles.
Take a few seconds to slowly come back to a standing position while leaning against the wall.
