Imagine trying to touch your elbows behind your back. That’s the movement you should be aiming for!

This movement will help open up your chest, which can help your sternum pop. However, even if you don’t hear a pop, you’ll likely get some pain relief just from stretching. You can do this exercise while you’re standing, or you can try it sitting down if you prefer.

Stop doing this stretch if you feel any tingling in your chest, shoulders, or back.

Your sternum may crack when you move into the cow position.

Since your shoulders stay on the ground, this exercise can lengthen and stretch your sternum, which may cause it to crack.

If you can’t breathe in through your nose, it’s fine to breathe through your mouth instead.

This expanding movement is what may pop your sternum for you.

As you breathe, focus on relaxing your neck and shoulders. Try to breathe out the tension you’re holding there.

Your doctor may be able to help you determine whether your posture, sleeping position, or exercise habits might be contributing to your discomfort.

Other signs of cardiovascular issues that you need to be aware of include a burning or crushing feeling in your chest.

If you don’t seek medical help, you could make the injury worse.
