What makes the PowerBall unique is its ability to operate on the principle of centrifugal force, generating variable resistance that automatically adapts to the user's training level. This makes the PowerBall an exceptionally versatile and adaptable training device. At an impressive speed of 16,000 revolutions per minute (RPM), the PowerBall generates approximately 16 kg (35 lbs) of lateral force.

With this groundbreaking technology, the PowerBall provides an effective way to strengthen muscles and improve overall fitness, even under the demanding conditions of zero gravity. It is an excellent example of how scientific innovation can contribute to the development of advanced training equipment for specialized applications, such as astronaut training.
