Though rolling a frying pan might seem a little random, it's a pretty common display of grip strength among strongmen and strongwomen.
Grip strength is a measure of how much force or power you can create with your forearm and hand muscles. It's important because you work those muscles every time you groceries, walk the dog, or lift a heavy object.
“When you’re doing a workout with challenging weights, grip strength is often the first thing to fail,” Liana Tobin, CSCS, a personal trainer educator for the National Strength and Conditioning Association, told Women's Health. “That’s because it involves smaller muscles that tire quickly, and they’re typically trained less frequently.”
Kat Ellis, CSCS, coach at The Fort in New York City told Women's Health that “having good grip strength will help you focus on proper form and mechanics, which means you’ll be able to push yourself to necessary fatigue levels.
