Lunges are an excellent exercise to stretch and develop the Quadriceps, the Hamstrings and the Glutes as well as the muscles of the hips.
How to do:
1. Stand upright with your feet shoulder width apart.
2. Step to the side while stretching your groin muscle. Once the stepping foot is planted, the upper body and the side knee should not move forward during the lowering and raising of the body.
3. Keeping the upper body vertical, dip your lower body straight down until straight knee comes close to the ground.
4. Hold the tension in the side leg, then raise your body straight up and return to starting position.
5. You may do repeated repetitions on a single leg before switching or alternate legs.
