ArmSport WristBall Wrist Trainer

The spherical shape forces your hand into a more natural, cupped position, which better mimics the mechanics of an actual arm wrestling match. Unlike flat straps that can dig into your skin, this ball distributes pressure evenly, allowing you to focus entirely on wrist flexion and forearm engagement.

While it is specifically engineered for arm wrestling techniques like the hook and top-roll, it is an excellent tool for anyone looking to build functional forearm strength. The ergonomic grip makes it a versatile addition to any routine focused on wrist stability and crushing power.

The 175 lb limit applies to the entire assembly, including the high-density silicone ball, the polyester strap, and the stainless steel D-ring. It is built to handle significant resistance, but you should ensure your loading pins or cable machines are rated accordingly.

The 65 mm diameter is a standard size designed to accommodate a wide range of hand sizes. It provides enough surface area for a secure grip without being so large that it prevents you from achieving the proper cupping motion necessary for effective training.

The high-density silicone is specifically chosen for its durability and resistance to deformation. It is designed to withstand the stress of heavy loads and frequent training sessions without losing its shape or structural integrity.
