The overhead press targets the shoulders, but is also an excellent overall exercise. Because not everyone has the necessary equipment to do a heavy overhead press, using a resistance band is a good way to make this move portable. The resistance band will help you build plenty of shoulder and arm strength, plus you can scale the level of resistance you're getting from the band to match your strength level.
These exercises work similar muscle groups to the push-up, but they all train your muscles at various angles, which means a more symmetrical and well-rounded upper body overall. And while the push-up truly is a fantastic upper-body exercise that works the chest, shoulders, and arms, it's by no means your only option.
So if you're tired of thinking you have to do push-ups all day long to get that upper body you've dreamed of, give some fresh exercises a try.
