I'm Jeremy Shore for LIVESTRONG.COM. Today, we're talking about the standard vs. the narrow push-up. The difference is going to lie in the hand placement and in the muscles that are addressed. For the standard or the wide-grip push-up, the hands are going to be placed slightly wider than shoulder-width, and we're really going to target the pectoral muscles and the anterior deltoids. While in the narrow or the close grip push-up, our hands are going to be positioned closer together, and we're going to be targeting more of the backs of the arms, the tricep muscles, as the elbows are brought in and tucked into the sides as you perform the movement. Let me show you. In the wide grip push-up, our hands are positioned slightly wider than the shoulders. Going to form a straight line, ear to ankle, abs tight, glutes tight. We'll lower ourself to the floor, elbows go out to the sides, and press back up. We're really targeting the chest muscles, the pectorals. If we want to move in our hands slightly to a narrow position, our close grip push-up, we'll actually tuck our elbows into the sides as we lower ourself, to add emphasis to the backs of the arms, the tricep muscles. I'm Jeremy Shore for LIVESTRONG.COM, and this is the standard vs. narrow push-up.
