Want to train like the American Ninja Warriors? Atomik Ninja Balls are the top training devices for building forearm strength and obstacle course competency. This product measures 9 inches in diameter.
As seen on NBC's American Ninja Warrior Cannonball Alley, the XXL Cannon Ball is an advanced-level pull-up ball meant to build forearm and upper body strength.
Its large, spherical shape forces the hand into an open grip position, targeting forearm muscles specifically. Our 9" Cannon Ball is a versatile pull-up training tool and can be used in a variety of different style workouts.


At a time when homewalls continue to be a significant and growing segment of the market, claiming the crown of Favorite Homewall Holds is no small feat. Atomik Climbing Holds, which has been making high-quality shapes for nearly 20 years, continues to win the hearts, minds, and budgets of homewallers for the third year in a row, beating out other close competitors. Atomik also has strong showings in the other homewall categories and is the only brand to place in the top four in all three Favorite Homewall Holds, Volumes, and Board System votes.

Homewallers are often highly focused on training, have limited space on their homewalls, and are operating on much smaller budgets than traditional gyms. Atomik has become a very appealing choice for this market, largely because of three key components: fast turnaround time, affordable, and a variety of training products. Atomik runs a 7-day, in-house manufacturing operation, which allows us to adapt to the immediate needs of our customer base. “Because we continue to manufacture our brand, this allows us to pass the savings on to our customers,” says Kenny Matys, owner and shaper at Atomik.
