The plie squat can be done using a foam roller. You can begin the exercise by standing straight with your toes pointed outward and your heels about a foot apart. Place the roller about a foot away from your left toes. It should lie perpendicular to your body. Squeeze your abs as you place your left foot on the roller so that your toes continue to point outward. Bend at the knees and lower your body toward the ground until your right thigh is parallel to the ground. Rise and repeat.
