If you’d like to take some gentle exercise that can strengthen your wrist and forearm, there are various ways of doing it, which we’ll come to later. And a strong wrist and forearm are very important if you’re into racquet sports, such as tennis, or sports like golf.

You can use a tennis ball and squeeze it - that’s an old standby. But there’s a more modern way too. Using something called the Powerball 250 you can use the power of the gyroscope to create a smooth and effective way to exercise.

Just by starting up a Powerball in your hand and rotating your wrist you exericse the wrist and muscles in your forearm. As well as being effective it’s quite fun, too.

The amount of ‘force’ you experience is a function of the torque produced by the Powerball 250 hz. You can influence the torque by moving your wrist faster or slower and controlling how far you move your wrist - smaller circles producing faster spin.

Powerball 250 hz pro weighs just a little more than a tennis ball, but it’s much more versatile because it produces a non-impact force which can be used for rehabilitation as well as strength improvements.

If you take the rotation up to 15,000 rpm you’ll experience nearly 40 pounds of pressure - imagine being able to put a 40 pound weight in your pocket! With something as small and portable as the Powerball you can truly take your exercise regime with you almost anywhere.

The powerball is not recommended for children under 14 and as with all types of fitness regimes you should seek the advice of your doctor before embarking on such a regime.
