STARTING POSITION:
Lie on your right side and place your right forearm under your head. Straighten your left leg and bend your right hip and knee around 90º. You can put your left hand on the floor. Raise your left leg as high as you can.
MOVEMENT:
Start doing circles with your left leg. Make sure your knee is always extended. Repeat the movement for the specified amount of repetitions and then switch sides and repeat with the other leg.
TIPS: Do the circles in both ways.
