DynaFlex Powerball Blue
- Welcome to the DynaFlex Powerball.
- Like the DynaFlex Pro, the DynaFlex Powerball delivers a surprisingly amazing workout as well as a tremendous light show.
- As the Gyro spins faster and faster, the LED lights flash faster and brighter, creating a spectacular light show and adding more fun than any workout you've tried.
- Have fun, be amazed and get strong as this Powerball revs up to 14,000 RPMs resulting in 38lbs of torque in the palm of your hand.
- Easy, fun and entertaining as you get the workout of a life.
- It may be fun, but its better than any toy when it comes to strengthening your arms, hands, shoulders, elbows and your grip.
- Used in space by NASA, as well as in the Military, Pro Sports Teams, Sports Trainers, Physical Therapists, and every day folks just wanting to increase grip and arm strength while having fun.
