Quadriceps

Phase 1

1. Lay on your side and flex the knee joint so your heel is approaching your buttocks.
2. Ankle should be plantarflexed so the toes are pointing towards the head.
3. Partner places one hand on the thigh to keep it in a straight line with the body and the other hand on the ankle pushing it towards the buttocks.
4. Stop pushing when sufficient pressure is felt in the quadriceps.

Phase 2

1. Exerciser attempts to extend the leg as if kicking a ball.
2. Partner tenses arms and ensures they have a stable kneeling position to withstand the pressure.

Phase 3

1. Repeat phase 1 but attempt to flex the knee joint further, whilst ensuring the upper leg stays in a straight line with the body so there is no pressure on the lower back.
