Describing the Iron Power experience is challenging at best, because you have never felt anything like it before. But imagine a sphere the approximate size of a tennis ball that feels as though you are lifting a 55 pound dumbbell when spinning at full speed. This may sound impossible, but it"s true. The faster the Iron Power Force Two Gyro spins, the more resistance is automatically added. This exerciser is perfect for the experienced Powerballer, Mixed Martial Artist or extreme athlete looking for a challenge or a way to get a competitive edge in their sport of choice. This training tool for arms, wrists and fingers makes use of the gyroscopic effect: Inside the housing, the circular movement of the hand sets a roughly 280 g heavy rotor moving. Just like with a spinner, the rotation builds up gyroscopic stability, which is higher the faster the rotor turns. But the greater the stability, the greater the force necessary to move the handtrainer, to unbalance the rotor"s stability at the same time. 10,000 revolutions per minute, the most powerful on the market. The handtrainer"s great advantage is that the training weight can be adjusted to individual requirement simply through the movement of a hand.
