Step by step instructions
Begin in a modified pushup position, with knees on the floor, toes tucked under. Maintaining a neutral spine, bend elbows and lower chest to the floor (tapping chest to the floor if possible).
Extend arms and straighten legs, coming into a plank position, drawing abs in tighter to spine. Hold for 1 count. Return to starting position. (Make the move harder by starting in a regular pushup position with legs straight. Do a full pushup, then lightly lower knees to mat during plank.)
