A cable pullover is an isolation exercise that works the back, chest, and abs—and it's one that'll come in handy when you're trying to build mass and get muscle definition in your upper body.

Mastering the form required to do the cable pullover properly (and making sure you don't hurt yourself using the cable machine), however, is not something a lot of people take the time to do.

But you're not just any average Joe in the gym, so follow these crucial tips when performing a cable pullover:

- Keep your shoulders, back, and chest up 

- Hands shoulder-width apart

- Keep your elbows slightly bent

- Drive weight with the elbows

- Control movement

- Pause at the top of the move
