Epic Grip - Arms Redefined.
The smallest, quietest and most powerful model in the current main Powerball product range, Powerball 350Hz Diablo Pro focuses up to 60lbs+ of gyroscopic inertial resistance directly onto the wrist and forearms and is one of the most efficient forearm workout, wrist and hand grip strengtheners available on the market today.
Yet at low spin speeds, the small shell size allows 350Hz Diablo to fit snugly into the hand where its smooth, 100% non-impact resistance can gently rehabilitate elbow tendonitis, carpal tunnel syndrome, tfcc tear, repetitive strain injury, wrist pain, tendonitis wrist and numbness in hands. Used just 5 minutes each day at these low speeds, this medically approved product will also help to dramatically improve strength and flexibility of the wrist joint and reduce overall recovery time from injuries like scaphoid fracture, broken / sprained wrist and forearm.
Small, compact and always ready to use, simply wind the cord around the rotor (see video above), give it a fast pull and start spinning - the faster you rotate your wrist, the faster the rotor will spin inside and the more resistance Powerball will create, leaving you pain free and strong from finger to shoulder and building powerful upper limbs in a fun, engaging way that's totally unlike any form of exercise you've ever experienced. Powerball Diablo is supplied in a clear perspex storage case that keeps it safe and dust free in between uses.

Powerball gyroscopic spheres provide unique isometric resistance for fingers, hands, wrists & arms
Build Powerful Forearms
Spin fast for 5 minutes to really pump the forearm flexors & extensors. Powerball exercises the arm in a way that simply isn't possible with regular isotonic (free-weight) exercise training, engaging a much higher percentage of muscle fibers in a far shorter time frame
Build Powerful Wrists And Grip
For the 1001 sports that rely on strong wrists and grip strength, there is nothing on the planet that builds it faster - Powerball helps develop muscle power & endurance quickly and efficiently, allowing you hit harder, cycle further and climb higher
Build Finger Strength & Dexterity
Finger grip strength comes directly from the flexor & extensor muscles in the forearm. Slowly spinning Powerball while gripping the sphere only with the fingertips will rapidly build [massive] grip strength, creating strong, nimble & highly dexterous fingers in the process
Wind, String, Key or Drum
Whether playing a drum, piano, sax or guitar, a musician needs to have strength, co-ordination and dexterity in their fingers and hands. Powerball helps increase agility, speed, accuracy & endurance - if it can make music, Powerball will help you play it better
Miracle Worker for Hands, Arms, Wrists
Our lifestyle choices today promote RSI injuries in the arms & wrists more than ever before. Gently spinning Powerball for 2-3 minutes during the day stimulates blood circulation, warms & loosens out tight muscle and reduces tendon inflammation, helping keep fingers, hands, wrists & arms pain free and mobile
Spins at 380 Revolutions Per Second
Powered just by your hand & wrist, Powerball is one of the fastest "human powered" devices on the planet and is a highly addictive, highly competitive and fun way to build powerful arms and wrists.
Easy to pick up but impossible to put down again, how fast will you spin it?

also product is extremely well made and packaged superbly i just love it.
Just beware when buying the heavier metal one as it seems more fragile,
If it wasnt dameged it would get 5 stars
It has increased my hand grip immensely. You can spin this at low speeds for recovery which is ideal for me. Took me around 45 minutes initially to figure out the correct motion but I blame myself more than the product for that.
