Lie on your back. Draw the injured leg up towards your head so that the muscles in the back of the thigh become increasingly stretched. Perform the exercise with outstretched as well as bent knee. Hold the position for 20 seconds and relax for 20 seconds before repeating. The exercise can also be performed standing with the injured leg outstretched on a chair while the upper body is bent slightly forwards.

Stand with support from the back of a chair or the wall. Using your hand, bend the knee and draw the foot up and your knee slightly backwards so that the muscles in the front of the thigh become increasingly stretched. Hold the position for 20 seconds and relax for 20 seconds before repeating. The exercise can also be done lying down. If you lie on your stomach you can draw the foot up by using a towel.

Squat with the injured leg outstretched behind you as far as possible with the foot on a box. Thrust your hip forward and down without swaying your back so that the front of the hip becomes increasingly stretched. Hold the position for 20 seconds and relax for 20 seconds before repeating.

Stand with one leg outstretched and the other slightly bent. Thrust your weight to the side over the bent leg so that the inner side of the opposite thigh becomes increasingly stretched. Hold the position for 20 seconds and relax for 20 seconds before repeating.

Stand with your hands on your hips and slowly sway your back, pushing slightly with the hands to increase the sway, so that the stomach muscles become increasingly stretched. Hold the position for 20 seconds and relax for 20 seconds before repeating.

Stand with the elastic around the injured leg, facing away from the elastic. Move the leg forwards and slowly backwards. The elastic can be moved up and down the leg depending upon the strength of the knee – the stronger the knee, the lower the elastic should be.
