3-1/2" Hanging Ninja Balls (Set of 2)

Grip strength training devices for Ninja Warrior, parkour, gymnastic, and climbing athletes.


If you're an American Ninja Warrior athlete or training to become one, the Atomik pull-up ball line is a necessity. These 3.5" climbing balls are a good beginner-level workout device; they're easier to hold on to than the larger spherical balls, so they're excellent for athletes just beginning to build forearm strength. Their shape and ability to rotate make these pull-up balls easier on your tendons and shoulders.
