What do diamond push ups do?

Answer 1

This variation is performed with your hands close together underneath your chest, the thumbs and forefingers of each hand touching each other. You lower yourself until your chest touches your hands and then push yourself back up. Diamond pushups places more stress on your triceps and will really help to fill them out. A folded towel will provide cusioning for your hands. It's a normal pushup done with your hands positioned in a diamond shape manner, such that your index fingers on both hands are touching one another, as are your thumbs.
