Squats are important for building thigh muscles, shaping the buttocks and improving endurance.
Place your feet shoulder width apart and keep your back straight and head up. Then squat down to where the tops of the thighs are parallel to the floor, hold for a second and then stand up. Use a fluid motion during this exercise and exhale as you stand up.
A lunge is great for working out your gluteus and hamstring muscles.
Start in an upright position and then step forward with one leg while keeping your abdominal muscles tight and your chest up. Lower your body by bending your forward leg as far as is comfortable but that your knee does not go forward beyond your toes, then push directly back up. Do all your reps on one leg then switch legs and do all your reps on the other leg.
