• Advanced Gyroscopic Resistance: Curaball hand exerciser adopts advanced gyro structure. The faster it rotates, the greater the resistance. It covers everything from warm-up to explosive power, helping you to accurately train the hand, wrist and forearm muscles
• Easy To Start: The torque ball uses a built-in pre-tensioner to start, and no starting rope is required.You only need to push the core in the direction of the arrow, When you can't push it anymore, release your finger and the internal spring will start the rotor, very easy and convenient
• Start-up method:This upgraded version features a built-in pre-tensioner for activation—no starter string required. Simply press the inner ball with your thumb and move it in the direction of the arrow to engage the internal spring. The mechanism is simple and eco-friendly. As the wrist rotates, the core spins at high speed, generating centrifugal force. The faster the spin, the greater the resistance, allowing the wrist to experience an effective workout
• Suitable for assisting: Long-term use of computers or mobile phones, carpal tunnel syndrome, repetitive stress injuries, etc. are more common. By continuously and indirectly strengthening the muscles and flexibility of the forearm and wrist joints, it can significantly improve muscle strength, flexibility, and promote blood circulation
