ARMSPORT WristBall – Wrist & Forearm Trainer

The ARMSPORT WristBall is a versatile wrist and forearm trainer designed for arm wrestling, climbing, bodybuilding, grip training, and strength development. Its unique 2.6-inch (65 mm) silicone ball provides a natural gripping surface, while the embedded strap connects directly to a resistance source.

Connect the WristBall to a cable machine, resistance band, or loading pin with weights. Then, use it to train your wrist, hand, and forearm through a wide range of movements.

Pronation, Supination & Cupping Training

The WristBall provides a simple and effective way to train rotational and lateral wrist movements.

Use it for:

• Pronation training
• Supination training
• Wrist radial deviation
• Wrist flexion
• Cupping
• Grip strength exercises
• Forearm training

In arm wrestling, wrist radial deviation is commonly called cupping. The WristBall lets you train this movement while maintaining a natural grip around the 2.6-inch ball.

Furthermore, the embedded strap allows you to position the resistance in different directions. This gives you more freedom to target specific wrist and forearm movements.

2.6-Inch Silicone Ball with Embedded Strap

The ARMSPORT WristBall features a durable 2.6-inch silicone ball that provides a secure and comfortable gripping surface during training.

An embedded strap runs through the ball and creates a strong connection point for your resistance equipment. Connect it to a cable machine for controlled training, attach it to a resistance band for portable workouts, or use a loading pin to add weight.

The WristBall can withstand loads of up to 200 kg, making it suitable for demanding strength training.

WristBall for Arm Wrestling Training

The WristBall is especially useful for athletes who want to develop the wrist and forearm movements used in arm wrestling.

Train pronation, supination, cupping, wrist control, and grip strength with adjustable resistance. You can also change the direction of the cable or resistance band to create different lines of force.

As a result, the WristBall can become a versatile part of an arm-wrestling training setup.

Grip Training for Climbers

The rounded silicone shape also makes the WristBall useful as a grip strength trainer for climbers.

Use the WristBall with resistance equipment to challenge your fingers, hand, wrist, and forearm. For an additional bodyweight challenge, connect two WristBalls to a pull-up bar and use them as independent gripping points for pull-ups and hanging exercises.

This setup creates a demanding gripping surface that challenges grip control and supports climbing-specific strength development.
