This video shows you how to do a classic gym exercise - the push-up. When done correctly, the push-up is a wonderful core exercise that's great for the triceps, deltoids, and pecs. To do a push-up, keep your elbows tucked in close to the sides of your body, which puts the shoulders in an optimal position to perform the movement, and ascend with your shoulders, stomach, and hips at the same rate.
