Narrow Push-Ups/Chest Muscles

Push-ups for the chest. Lie on the stomach and make fists with the palms. Press them inward on the ground and push yourself off the floor. The entire body is fully extended lengthwise. The toes are on the ground. The body forms a straight line. Now push the arms up and then come back down until the chest is just above the ground. This is done in a continuous alternating motion.
