La-VIE Power Wrist Training Ball 3B-1075 [Manufacturer's Genuine Product]

The La-VIE "Power Wrist" is a gyro-style training ball that uses the centrifugal force of a rotating ball to train wrist, grip, and arm strength. Pulling the string starts the rotation, and rotating your wrist increases the rotation speed and thus the resistance. Despite its compact size, it allows for serious muscle training.

The main unit measures approximately 7cm in diameter and 6.2cm in height, and weighs approximately 220g, making it lightweight and easy to carry. Made from ABS, steel, and polycarbonate, it boasts excellent durability. You can easily train your forearms at home or in the office during short breaks.

The high-speed rotation targets snapping power and grip strength, making it ideal for those aiming to improve their athletic performance. It stimulates muscle strength from the shoulder to the fingertips in a balanced way, and can also be used for rehabilitation and maintaining health.

The stylish green and black color scheme is perfect for those who care about aesthetics. The resistance changes simply by rotating your wrist, making it suitable for a wide range of users, from beginners to advanced. It's a highly versatile item as a muscle training tool.

The string-winding start system makes operation simple. It's said that once you get used to it, the feeling of the spinning ball "going wild" becomes addictive. It can also be used to check grip strength and forearm muscle strength, making it easy to see the results of your training.
