stitch

Beginner ⚽ Sports / Fitness

Definition

A sharp, localized stabbing pain that hits under your ribcage during intense exercise—your body's way of reminding you that you're out of shape. Not to be confused with the sewing kind, though both are equally painful.

Example Usage

I had to stop the sprint workout because I got a brutal stitch in my side halfway through.
