280Hz Autostart Pro

hand and wrist pain

The all-rounder for strength & recovery

At only the size of a tennis ball, Powerball 280Hz Autostart Pro is a small but mighty exercise device designed for strength & rehabilitation. Spin this powerful gyroscope at fast speeds and feel the muscles in your arm start to burn. Spin it at slow speeds however, and you’ve got yourself a fantastic tool for injury recovery and prevention. We recommend using Powerball for just 1-3 minutes everyday and you should soon start to feel the difference. Spin your way to stronger arms, greater grip power, more resistant muscle and of course, long-lasting recovery.

  • LCD Speed counter
  • Generates up to 16kg in resistance
  • Spins at up to 18,000rpm
  • Polycarbonate shell
  • No batteries, no cords
  • For strengthening & rehabilitation

Build Grip & Arm Power

As you spin Powerball it generates resistance - the faster you spin, the stronger the resistance will be. Harness the immense power of 280Hz Pro at fast speeds (up to 18,00rpm!) to build solid upper arm muscles, a stronger wrist and the ultimate grip.

Strength Training With No Risks

The resistance Powerball generates is called ‘isometric resistance’. Isometric resistance engages a much higher percentage of muscle fibres than standard isotonic training (e.g. free weights) does. It is also non-impact, making it a form of strengthening that places ZERO strain on your muscles as you exercise. It’s weight training with none of the injury risk.

Injury Recovery & Prevention

At slow speeds Powerball can provide almost instant pain relief and fast, effective treatment for injuries such as RSI, carpal tunnel syndrome, tendinitis, muscle tears, tennis/golfer’s elbow and broken bones or sprains. Its non-impact resistance also means it won’t cause further damage. Read more about how Powerball can rehabilitate a specific injury in the ‘instructions’ section of this website.

LCD Speed Counter

280Hz Autostart Pro is fitted with a 4-mode Acura 2.0 LCD speed counter for easily monitoring your strengthening progress. Get an exact reading on your spin speeds every time - the counter also saves your highest spin speed for 24 hours. No battery required, the speed counter is powered solely by the magnetic inertia of the spinning rotor!
