The sumo squat works all leg muscles, although it can also be used to target the inner thighs. This exercise can be performed with or without weighted resistance. The key to this exercise is to stand with the feet beyond shoulder width. The wide stance forces the inner thigh muscles to work harder. The toes should be turned out.
Once the feet are in position, hold the medicine ball in front of the body. The arms should hang freely during the movement. Squat down until the legs are parallel. A partial movement (e.g. half way down) is okay for those with limited mobility. Be sure to keep the back straight and head up. Exhale as you stand up.
Stand with the feet wide. The ball should hang freely in front of the body.
Squat down until the legs are parallel to the floor.
Return to the starting position and repeat.
