Begin by laying on either said, let's start with your right. Support your upper body by leaning on your right elbow in a comfortable and supportive position. Rest your legs and hips on the floor with your legs in a bent position.
With your left arms resting on your left thigh, slowly raise your hip off the floor until you form a straight line from your head to your knees. Your knees will remain on the floor.
Hold and lower back slowly. Repeat with other side.
As with most static contraction and plank exercises, you can increase the difficulty by holding the position for a longer period of time.
