Arm booster gripsOur Arm Booster Grips help improve your training by activating more muscle fibers with every pump.Boost your strength, your biceps, forearms, and grip, and build stronger arms way faster.
WHY A THICKER GRIP?Training with a larger-diameter grip engages more muscle fibers, especially in the elbow flexors (biceps, brachioradialis, and brachialis) and smaller stabilizer muscles in the hands and wrists that aren’t used much when lifting standard-sized weights. Your hands and forearms are under a greater amount of tension for a longer period of time, and increased time under tension is beneficial for muscle and strength gain. BETTER GRIPYou’re only as strong as your weakest link. Incorporating wider grip training into your routine for selected exercises can help you address grip weaknesses and improve your strength and hand strength, as well as increase forearm muscularity, resistance (weight) on pulling exercises and deadlifts, and overall endurance and dexterity. HOW TO USEThe Arm Booster easily wraps around barbells, dumbbells or any other handle. 
A MORE COMFORTABLE GRIPThe Arm Boosters are made from our impact-reducing RevoFoam, which means these grips are softer on your hands than regular iron dumbbell and barbell bar grips, leading to less calluses after your workout. LEVEL
