More comfortable than strap training and capable of handling heavier loads, the WristBall is the go-to training tool for developing serious wrist strength.
Superior Wrist Strength Training for Serious Arm Wrestlers
Traditional strap training has its limits. It’s uncomfortable and restricts how much weight you can use. The WristBall changes that. Its ergonomic, ball-shaped design makes it comfortable to grip, while its durable construction allows you to progressively load more weight to push your wrist strength further than ever before.
Whether you’re working on rising, pronation, or supination strength, or looking to sharpen your hook and top-roll techniques, the WristBall gives you the edge to dominate every match.

Heavy-Duty Durability: Made from high-density materials that can handle intense, repeated training sessions.
