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.

Lie on your back with one leg outstretched and the other bent with the foot on the other side of the outstretched leg. Draw the knee up towards the opposite shoulder so that the buttocks become increasingly stretched. Hold the position for 20 seconds and relax for 20 seconds before repeating.

Seesaw. Balance on two legs, possibly using a hand as support against the wall, balancing subsequently on one leg without support. Look straight ahead and keep knees bent.

Stand with your back against a wall with a ball or firm round cushion between the wall and your back. Slowly go down to bend your knee 90 degrees before slowly rising up again.

Stand on the healthy leg with the elastic around the inside of the injured leg. Move the injured leg from side to side in a slow smooth movement. Moving the position of the elastic lower down the leg can increase the load.

Stand on the healthy leg with the elastic around the outside of the injured leg. Move the injured leg from side to side in a slow smooth movement. Moving the position of the elastic lower down the leg can increase the load.

Lie on your back and bend the injured leg. Lift the healthy leg, and then raise your backside with the weight on the injured leg to be trained. Hold the position a few seconds and lower your backside again. Moving the injured leg further away from the body will increase the load.
