상품 특징

• 【Torque Ball Auto-Start + LED Light Design】 This torque ball hand exerciser upgrades to a built-in pretensioner (no starter cord needed): press the inner ball with your thumb, twist along the arrow—its internal gyro spins at high speed (with dynamic LED lights) to generate centrifugal wrist resistance, making training fun and visible.
• 【Real-Time Progress Tracking】 The self-powered torque ball comes with an LCD counter to auto-track RPM, training time, and energy expenditure, helping you clearly monitor grip strength and endurance improvements after each session.
• 【Compact, Lightweight & Easy to Use】 No buttons or settings needed. Simply press and twist to activate. The non-slip silicone grip ensures comfort during daily training at home, work, gym, or on the go.
• 【Ergonomic & Portable】 Features a non-slip silicone grip and lightweight design; no buttons/settings required, just 5 minutes daily for noticeable results. Take this torque ball hand exerciser anywhere (home, office, gym) for convenient training.
• 【Premium Gyroscopic Technology】 Uses aerospace-grade gyro tech for smooth, adjustable resistance, suitable for athletes, musicians (guitarists/pianists), and sports-loving kids. It’s also a chic gift for daily hand & wrist training.
