Diamond Push-ups

Diamond push-ups it's a variation of the original push-up that works your arms and your chest at the same time. To do this exercise, all you need is to get in the original push-up position but with your hands doing a diamond position (with your thumbs doing the lower part and the rest of your hands doing the upper part), and then you go up and down with your elbows turned out as much times as you can handle.
