Lie on the floor face down
and place your hands about 3 feet apart while holding
your torso up at arm’s length. Next, lower yourself downward
until your chest almost touches the floor as you inhale. Now breathe out and press
your upper body back up to the starting position while
squeezing your chest. After a brief pause at the top
contracted position, you can begin to lower yourself downward
again for as many repetitions as needed.
