Instructions
Get yourself in the push-up position with your hands flat on the ground just wider than shoulder width apart.
Ensuring that there is a straight line running from your neck to your heels, lift your right leg off the ground.
Keeping your right leg elevated, bend your elbows and lower your body towards the ground until your chest is about two inches away from the floor.
Push your body back to the starting position and then lower your right leg to the ground.
Repeat the motion with the left leg elevated.
