Gyroscopic Forearm Muscle Builder

The new Powerball Iron Series is built for those who demand more from their training. Designed to push limits, this gyroscopic powerhouse delivers elite-level grip strength, wrist endurance, and forearm development—all in a compact, beautifully engineered device.

Note: Not compatible with Gyroscope Speedmeter.

Engineered for Maximum Resistance

The Powerball Iron is a precision-crafted forearm muscle builder, capable of generating up to 16,000 RPM and delivering 50–60 lbs of dynamic, gyroscopic resistance. Its ultra-smooth spin provides a fluid, continuous challenge to your grip, wrist, and forearm muscles—perfect for athletes who need real, measurable strength gains.

Stylish and Functional

With its polished metal finish and compact form, the Powerball Iron doesn’t just perform—it stands out. Whether on your desk, in your gym bag, or at your training station, it brings both form and function in one sleek design.

The faster you spin it, the harder it pushes back.

This progressive resistance is ideal for:

• Advanced users seeking new levels of intensity
• Combat sports athletes improving grip and reaction speed
• Rock climbers, weightlifters, and MMA fighters building forearm endurance
• Anyone serious about grip strength, coordination, and muscular endurance

Take Your Training Further

Whether you’re recovering, training, or leveling up, the Powerball Iron Series delivers the resistance and results of a true forearm muscle builder. Experience powerful motion, superior engineering, and elite performance—in the palm of your hand.
