The Source is selling Powerball imitations for $9.99 (regular price: $19.99). The Powerball or its imitation is basically a gyroscope in a casing. As a gyroscope rotates and builds up angular momentum it exerts force on the ball, and your hand in turn. You rotate the ball in circles through the air to keep the gyro going faster, and faster, which in turn produces more force on your hand. It’s a very simple and fun-to-use exercise ball and best of all, it can help prevent wrist injuries and stave off Carpal Tunnel Syndrome. It will also build your forearms, and really exercise your hands and fingers. Here’s a video that explains the Powerball more.

Should you buy The Source’s imitation or original Powerball?
Original is much more expensive (about $30 and up).

Buy powerball imitation if:
– You need it to avoid Carpal Tunnel Syndrome or exercise your hands.
– You’re trying it out for the first time.

Buy original powerball if:
– You want to seriously build your forearms and you’re interested in strength-building.
– You just have an unlimited supply of money 🙂

The Source has two different models on sale:
Wrist Exercise Ball
Nexxtech Wrist Ball
