Mitsubishi Precision of Japan has fitted weightlifters鈥� barbells with
gyroscopes to provide a more balanced work-out. A small motor drives the gyro
inside one of the spheroidal weights, powered by batteries inside the other.
鈥淲hen you exercise with normal barbells you are just fighting gravity,鈥� says
Hajime Sone of Mitsubishi. 鈥淏ut with the gyro, you are exercising against a
lateral force as well, which is much better exercise for the muscles.鈥�
