A minor adjustment to the way you do biceps curls could put bigger gains within your grasp.
Fat Gripz – plastic sleeves that increase the thickness of your dumbbells’ handles – force you to grip the weights in an unfamiliar way and could be just the shot in the arm your upper-body routine needs to spur new muscle growth.
“The fatter grip is going to cause increased activation of your forearm and biceps muscles,” says Men’s Health Fitness Director BJ Gaddour, who demonstrates in the video above how you can use fat grips to power up your dumbbell workouts.
Can’t get your hands on a set of fat grips? No sweat. “You can modify by wrapping the handle of a dumbbell with small hand towels,” Gaddour says.
