Whether you’ve got hand and arm injuries that need some work, or you simply want the firmest handshake in town – this device has got you covered. Called the Gyroscopic Dumbbell and used by NASA astronauts to maintain their upper body conditioning in space, it is able to produce up to 38lbs of torque resistance at up to 13,000rpm – strengthening your wrists, biceps, triceps, all the way up to your deltoids (those muscles around your shoulders).
Roughly the size of a tennis ball, the Gyroscopic Dumbbell’s ultra-fast spinning internal gyroscope gets rolling when rotated with your wrist and with a weight of only 1lb, can be conveniently carried around for a workout at home, at work or even on-the-go.
Thanks to a study performed by Southern Utah University, we know that the Gyroscopic Dumbbell can increase maximum handgrip strength by 11%, plus it can aid in the rehabilitation of carpal tunnel syndrome and also improve tennis elbow injuries. Some dumbbell, eh?
Equipped with a built-in tachometer that tracks and displays your current rpm, highest ever rpm and total revolutions, the Gyroscopic Dumbbell comes with a docking station and is available now from Hammacher Schlemmer for $69.95.
