Main muscles working (thicker lines)
Stand with your back flat against a wall and feet about hip-width apart, roughly two feet in front of the wall.
Slide your back down the wall until your thighs are about parallel to the floor.
Position your feet so your knees are stacked over your ankles.
Hold the position with your back flat on the wall and weight through your heels.
Slide back up the wall to finish.
Breathing: Breathe steadily throughout the hold; don't hold your breath.
Knees over ankles
Back flat on the wall
Weight in the heels
Feet too close so knees drift far past the toes
Resting hands on the thighs
Holding the breath
