Product Description

Adults and children alike will love the grip strength trainer they can bring with them, use any time, and see results. Whether that's strengthening your hands, building forearm muscles, or doing resistance training exercises, you'll benefit from the strength that this hand grip exerciser develops. Rock climbing fans, wrestling athletes, guitar players, and therapy patients all have one thing in common, they all improve their performance by increasing their hand and finger strength.

Your 321 STRONG silicone hand ring  works out the arm, wrist, forearms, hands, and fingers with 45 lb resistance, which is noticeable and satisfying, but not overwhelming or hard to use. Made of durable aqua silicone rubber and so fun to use you won't want to put it down. Develop pinch strength for the gym, squeeze away stress, loosen up stiff joints, all with our fun-to-use silicone hand ring.
