The NSD Powerball is a unique sports, fitness and rehabilitation device with a huge range of benefits. Used for sport it will strengthen and build important muscles in your fingers, hands, wrists, arms, shoulder and chest area that will improve your performance in golf, tennis, squash, basketball, cricket, rowing, cycling, mountain-biking, fencing, hockey, kayaking and countless other activities.
Using the NSD Powerball as an addition to your fitness regime you can tailor your workout to suit your individual needs. To tone and shape the arms, using the Powerball at a relatively low speed of 6000-8000rpm for around 7 minutes each day will add definition and shape without unwanted bulk. Alternatively, if your aim is to build muscle and bulk up, spinning the Powerball above 12,000rpm will give even the most powerfully developed arm a serious workout.
From a rehabilitation point of view the inertia (gyroscope resistance) generated within the NSD Powerball is directly proportional to the speed at which you are spinning the rotor, making the Powerball ideal to provide gentle recovery from a range of conditions including broken wrist, carpal tunnel syndrome, RSI. tendonitis, tennis elbow and golfer's elbow.
