A gyroscopic wrist powerball is a handheld exercise device that utilizes a gyroscope to generate resistance as the user spins it. These devices are often used for strengthening the muscles in the wrists, forearms, and hands. The gyroscopic effect is created by a spinning rotor inside the device, and as the user rotates their wrist, the gyroscopic force resists the motion, providing a workout for the muscles.
Adding LEDs to such a device could be for aesthetic or functional purposes. LED lights might be used to make the product visually appealing, especially in low-light conditions. They could also serve as a way to indicate the speed or intensity of the gyroscopic motion
