Powerball 250Hz Hanfd Gyroscopes
Sold out.
Description:
Powerball® is a finely engineered, high-precision gyroscope consisting of a rapidly spinning rotor enclosed in a solid [hand held] outer sphere.
The best products don't require a lot of fuss, they just work. Wind back the precisely balanced zinc rotor; release and begin turning your wrist in slow, gentle circles.
Speed builds rapidly inside the sphere, producing a powerful resistance which is just as effective for non-impact rehabilitation as it is isometric strengthening of the arm, all the way from fingertip to shoulder.
How does it work?
Regular exercise with Powerball® can help maintain muscle tone and health from finger to shoulder, thanks to its rhythmic movement and non-impact nature. When your muscles respond to the demands placed upon them from exercising with Powerball®, blood flow increases and joint health is promoted by stimulating the production of synovial fluid (the fluid that lubricates and nourishes joints).
The gripping action required to hold Powerball® activates the finger flexor muscles and the wrist extensor muscles. Activating the wrist extensors prevents wrist flexion, thereby enhancing grip strength. With the wrist extensors activated by the gripping action, the rotatory movements necessary to maintain the gyroscopic movement of Powerball® exert forces on a wide range of muscles.
