The sound that you hear when you stretch your chest upwards. Most of the time, it will be painful but will feel good at the same time.

The causes are usually hunching or benching more weights than what you can lift.

After you have popped your chest, it takes about 6 or more hours until you can perform it again.

Brendon: Have you tried holding your breath while you're doing it?

McGuirk: Dude! Did you hear that? That was one of the loudest chest-pop I've made. It hurts and feels awesome at the same time.

Melissa: You're weird.
