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 knees. Your body should be in a straight diagonal line from head, shoulder, hips to knees. Squeeze your abdominal muscles tight to support your body in this position. Keep your arms straight but not locked at the elbows.

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.

Do 12 reps, rest and repeat.
