Dynaflex Power Ball Amber Box, Amber LEDs Glow as the Speed Increase

Dynaflex Power Ball the faster it spins, the stronger you get!

The Dyna-Flex powers up with the rising pitch of an F-18 fighter - with no batteries, no motor. Yet we dare you to hold on to it! Give it a quick pull or thumb flick to get it moving. Rotate your hand. It starts to race and hum. Soon it's whirling at over 9,000 revolutions per minute! Meanwhile, your wrists, grip, and arm are straining and working out against a powerhouse gyroscopic action. In fact, Dyna-Flex is now spinning internally so fast that it wants to leap out of your hand! Need a break? Slow down the rotations, or pass it on to an unsuspecting friend. Watch them try to hold onto it! As an executive relaxer, a carpal-tunnel / arthritis reliever, or a strength and coordination builder, Dyna-Flex will knock your socks off!

The Dyna-Flex Powerball makes the cover of Time magazine as one of their top 10 digital devices of the year. It features a balance rotor and removable top cap, which allow insertion of the optional digital speed meter. Generates from 32lbs to 35 lbs of torque when speeds of 9,000 - 13,000 RPM's are reached. The ultimate in engineering design, featuring the same user-friendly features as the Dyna-Flex Pro Plus but incorporating an on board generator. By activating the gyro, a dynamism (motion) is created, which will activate LED lights, located in the interior of the gyro. The faster the unit runs, the brighter the lights will be until the whole hand is engulfed in a bright glow. Just when you think you've seen it all, along comes the ultimate hand, wrist and arm Exerciser, the Dyna-Flex Powerball.

Powerball gets going easily with the flick of a thumb or a quick pull of its starter cord.

Rotate your wrist to make the balanced rotor spin faster and faster, up to 13,000 rpm.

Blue LEDs glow brighter as the dynamic powerhouse gains speed.

Its 35 lbs. of gyroscopic force creates progressive resistance.

Improves coordination while building strength in your fingers, hand, wrist, arm and shoulder.
