It's like a rapidly spinning vortex in your hand; the faster the engine spins, the more inertial resistance it generates, working your arm harder and harder until your muscles are burning and screaming for you to stop. And because it’s pure isometric resistance, Powerball engages almost the entire group of fibers in each muscle that it’s exercising, ensuring that you’ll reach fatigue in a much shorter time frame than with traditional exercise methods (in fact - less than 30 seconds if you really accelerate the Powerball’s rotor speed)
Put down your dumbbells and take a fresh look at the way you exercise - small balls really can build arms of steel.
A Look at Powerballs
The lightweight powerball is designed to be held in the hand, so it’s about the size of a tennis ball. The outer shell of the ball encases the rotor, and when that rotor spins, it provides torque that causes the ball to rotate and jerk. Depending on the research, it has the potential of spinning of 9,000 to 18,000 rotations per minute, which in turn provides about 25 to 40 pounds of torque.

Effects of GyroBall
The GyroBall is typically used for strengthening and toning the muscles in the forearms. This can be beneficial for athletes such as basketball players, who use their forearms when dribbling and shooting. It can also help those who are hoping to be able to type on the computer for longer hours without becoming fatigued. It is also very effective for badminton players who want to have better net control and strong backhand.
The ball can be used for rehabilitation purposes for those who are recovering from carpal tunnel, arthritis or lower arm bone and tissue injuries. Because you control how much torque is applied, you can adjust the intensity of the exercises to accommodate your training goals. Powerballs can also be used to build strength and stability in the arms and shoulders by moving your arms as you spin the ball. Athletes can spin the ball while mimicking the throwing movement if a baseball player or a punching if a boxer. According to Dr. Sebastian Axel Balan’s 2008 study published in Hand Surgery, powerballs were found to increase forearm strength and endurance after four weeks of training and also improved the reflex activation of wrist muscles.
Using the Ball
The rotor of the GyroBall doesn’t spin on its own. To use the powerball, hold it in one hand so that your palm faces upward and rounds tightly around it. Flick the rotor with your thumb, and then immediately rotate your wrist to get the rotor spinning. The faster that you rotate your wrist, the faster the rotor will spin. You can spin the GyroBall in both directions. Some powerballs have a power cord to help you get the rotor spinning. Stick the end of the cord into the rotor, and then roll the rotor forward so that the cord wraps around the rotor three times. Pull the cord out quickly, and start rotating your wrist to continue the spinning of the rotor. Stop the rotor from spinning by gently touching it with your fingers.
The most basic way to use the GyroBall is to get it spinning and continuing to spin it for 30 to 60 seconds. Complete the exercise with both hands and by rotating the rotor in both clockwise and counterclockwise directions. Target your finger muscles by holding the ball in your fingers while the rotor spins. To work your biceps, hold the spinning powerball while your arm is down by your side and your elbow is bent to 90 degrees. Extend your elbow to lower your arm by your side and then bend your elbow again. Work your shoulders by lifting your straight arm up in front of you or out to your side until your arm is parallel to the floor, and then lower it back down to your side.
