Push-Ups are one of the world's oldest exercises. Unfortunately today, Push-Ups are only used by the military, as part of sport conditioning and to set records for the Guiness Book.
How to do:
1.Assume a prone position on the floor with your body weight supported by your hands and balls of your feet.
2. Your hands should be placed in line with your shoulders and your fingers should be pointed in at a 45 degree angle.
3. Lower your body until your chest nearly touches the floor and then raise yourself.
4. For variety your elbows can jut outward, remain close to the body or you can perform the movement between benches for a greater range of motion.
