This variation of an old favorite is a great way to add a little variety to your workout routine.
Start with the normal push-up position; feet on the ground, hands under your shoulders, core tight.
While maintaining a straight line between your shoulders, hips and ankles lower your chest to the ground, now press up to the starting position while breathing out. Move your hands out about 6 inches, now lower yourself back down and press up. Now again move your hands to the original position and repeat.
By changing the position of your hands you will stimulate different muscle fibers in the chest and it will also increase your gym coolness rating at least 10%.
