STARTING POSITION:
Lie on your side and place your right elbow under your shoulder. Straighten your legs and put your feet together. You can put your left hand on the floor in front of you. Squeeze your abdominal and oblique muscles.
MOVEMENT:
Rise your left leg as high as you can while you exhale. Make sure you don't bend your knee. Return to the starting position in a smooth movement while you inhale. Repeat the movement for the specified amount of repetitions, then switch sides and repeat the exercise.
TIPS: For a better glute activation, your toes should always point forward.
