♦ For the standing lunge, move your right leg straight back behind your body, flexing the right foot, and sink down. This causes your left knee to bend.
♦ For the diagonal lunge, move your right leg out at a 45-degree angle and sink down. This again causes the left knee to bend.
♦ For the lateral lunge, step the right knee out to the side and sink down, once again causing the left knee to bend. The important thing is to keep the left knee over the ankle.
