Solid Zinc Rotor

Diablo shares it’s high-precision solid zinc rotor with its cousins, Hybrid and Titan Powerball. Just like these Powerball models, Diablo Evo can spin at incredible speeds of up to 20,000rpm (rotations per minute), completely vibration free. This zinc rotor is far heavier than those inside our standard Powerball models and it can output nearly twice the resistance/torque - 27kg at max. speed.

Classic Model

The singular difference between Diablo Pro and Diablo Classic is that the ‘Pro’ model comes fitted with an LCD speed counter for measuring progress and recording spin speeds. All ‘Classic’ Powerball models are fitted with stylish, flat caps to round out the circular design and allow for better grip. These caps can easily be popped off and replaced with an LCD counter (sold separately) later if change your mind and want to upgrade to a ‘Pro’ model.

Built for Intense Strengthening

As you spin Powerball it generates resistance - the faster you spin, the stronger the resistance will be. Harness the immense power of Diablo Autostart Classic at fast speeds (up to 22,000rpm!) to benefit from intense strengthening that will seriously develop your arm muscles and grip strength.

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. In a nutshell - it’s weight training with none of the injury risk.

Injury Prevention

Diablo is designed to strengthen and reinforce the joints and muscles in your arm and wrist. Give it a quick spin every day to benefit from stronger limbs that are better protected from injury. Powerball is fantastic for combating the effects of repetitive strain injury (RSI), such as carpal tunnel and tendonitis, as well as breaks and sprains.

Enhanced Sport & Music Ability

An effective exercise tool that will dramatically improve grip strength and finger dexterity, Powerball is a great product for all serious athletes (golf, tennis, climbing, boxing, etc.) and musicians (guitar, drums, piano). Grip harder, move faster, play longer with Powerball.
