Start in basic plank position with your forearms on the floor. Draw one knee toward your elbow as far as you can without twisting or moving your upper torso. Push your heel back toward the starting position. Avoid allowing your foot to touch the floor before drawing your knee towards your elbow again. Repeat by drawing the other knee towards your elbow.
