You’ve probably put a lot of work into strengthening your upper body to make lifting, pushing, and pulling heavy loads a cinch. But what about your grip strength? Chances are unless you’re doing forearm workouts, it’s relatively weak.
What Forearm Muscles Do
The forearms are made up of a bunch of smaller muscles that move in four main ways, Pire explains wrist flexion (bending your palm inward), wrist extension (raising the back of your hand), forearm pronation (rotating the palm down), and forearm supination (rotating the palm up). Working all ranges of motion will help better balance forearm development, and therefore help with everything from opening jars to swinging a golf club, he adds.
Keep in mind, though, you’re probably building your forearms a bit without even realizing it. “Any exercise that involves gripping and more specifically pulling is going to place huge demands on the flexors of the fingers and wrists,” Pire adds.
