Powerball Mr Big

heavyweight class

— ideal for building strength and muscle mass

The housing is made of an extremely hard aluminum alloy.

Powerball® Mr. Big has a diameter of 82 mm and a total weight of 510 grams — making it 10 mm wider and more than twice as heavy as the classic Powerball®.

The heavy-weight rotor provides up to 50 lbs (22 kg) of resistance at about 10,000 revolutions per minute. With added weight and torque, muscles in the hand and forearm can be built even faster.

The new innovative shock-resistant housing structure prevents damage during a fall. The patented stability control system ensures vibration-free rotation and an incredible feeling in the hand.
