The Basic Bodyweight Press Up Exercise
1. Facing the ground adopt a position as shown where your body is straight and only your hands are feet are touching the ground (arms straight) - arms slightly wider than shoulder width.
2. Lower your body by bendig your arms (hands still in same place) until your chest is nearly touching the floor, then pause for a second.
3. Raise your body by straightening your arms until your arms are nearly straight, pause for a second then go back to 2.
Exhale as you go up, and inhale as you lower your body.
If you can't do a full push-up, do them on your knees, such that in the starting position, your body is resting on your hands and knees instead of your hands and feet.
