48. Diamond Push-Ups
Diamond pushups are a great way to work those shoulder and back muscles if you aim for a well-defined back to show off in the summer. What makes them work so great is that you’re forcing them to work overtime by shifting your center of balance. You’re also putting more weight on your triceps, so this is an excellent workout for your arms. Start in the pushup/plank position. Instead of your hands being under your shoulders, shift them closer together to directly beneath your chest. Lower yourself to the ground so that your elbows form a diamond shape when bent. Then push off the floor and raise yourself back to starting position.
