Diamond Push-ups are more challenging for most people than regular push-ups, requiring a certain amount of balance and strength. You do Diamond Push-ups by placing your hands close together making a diamond-like shape between your fingers, and thumbs. If you are not able to complete this exercise with that amount of spacing, then you can space your hands a bit farther apart. This type of Push-Up best works to build the middle of your chest, front shoulder muscles, triceps, along with other muscles. If you are trying to improve the look of your chest then regular sessions of diamond Push-Ups are a great benefit to you. Try working your way up to 30 push-ups a session, then maybe even farther beyond if you are able. Know your limits!
