Lie on your tummy. Place your hands wide apart, in line with your shoulders, elbows bent and fingers facing forwards. Now push yourself up on your toes. Your body should be in a straight diagonal line from head, shoulder, hips to toes. Arms will be straight but not locked at the elbows.

This is the start position.

Gently bend your elbows and lower your chest towards the floor, all the while maintaining your body in a straight line. The back should not sag downwards. Once you go as low as possible, "push up" to the start position.
