HOW: Begin the exercise in a forearm plank position with the knees straight. Perform the exercise by moving at the hip joint to lift one leg into the air while keeping the knee straight, hold that position, then return to starting position and repeat on the other side.
FEEL: You will feel your glutes and quads working to lift the leg as well as the rest of your body and core muscles working to maintain the forearm plank position.
COMPENSATION: Do not arch your back to drive the leg lift. Focus on lifting each leg while keeping the knee straight and the rest of your body still in the forearm plank position
