The 'plank' exercise is ideal to strengthen your back muscles. First, get down to the push-up position and then slowly down on the elbows. In this forearm position you keep your whole body tight and absolutely avoid a hallow back. Remain in this position for 30 seconds and repeat the exercise when required.
