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.

Lie on your side on a table. Bend one leg up under your body and let the other hang over the edge of the table so that the muscles in the outer side 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 standing by placing the outstretched injured leg behind the good leg at the same time as bending over the injured leg.

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.

Sit on a chair with elastic around the ankle, facing the elastic. Lift the leg and slowly bend and stretch the knee.
