Why it works: You can have the strongest biceps and triceps in the world, but if you don’t have forearm or grip strength, you’ll never be able to do the things that make you functionally fit — like picking up and hanging on to heavy loads. McCall says this exercise is one of the easiest ways to build forearm and grip strength, and ACE included it in its Best Grip Strength Moves roundup.
How to do it: Hold onto a barbell with an overhand grip. Curl the barbell up, with the backs of your arms leading the way toward your shoulders. Return to start and repeat. Do three sets of 12 reps.
