Overview
Reviews

If you're an American Ninja Warrior athlete or training to become one, the Atomik bomb/ pull up ball line is a necessity. These 3.5" climbing bombs are a good beginner level workout device; they're easier to hold on to than the larger spherical bombs, 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.

In order to hang your Bombs, we recommend using our Bomb Accessories

Are These For You?

If you want to practice simple ergonomic pull-ups these are for you.
If you want to improve your grip strength I recommend the 4.5" or 6" Bombs.

lots of fun

The fact that there are two is great because I use them as a ninja obstacle (in conjuction with other bombs/pipe bombs) or as a pull up apparatus with the added grip challenge.

A good challenge for beginners

This is the perfect size for beginners who want a challenge and want to work on open hand grip.

Bigger than expected

These bombs are bigger than they seem but worth it. one of the harder to conquer for sure but worth it in the long run for training ninja warriors of all ages

These started it all for me and should for you too

My ninja career started with bombs/cannon balls. 3.5" is the perfect size to start as well. Forget the bar and go with these for your pull ups and single-hand, unilateral- horizontal swings. Great way to build soft-tissue strength and start using those fingertips in a sneaky intro to sloper strength. When my athletes ask me what they should purchase to get started, it is definitely a set of 1.5" rings and a set of 3.5" bombs.

Great

These are a perfect for all ages and sized hands. These are some of the most comfortable cannonballs on the market. They are great quality and they are the size of a baseball.

Ideal for ceiling traverse across lava floors!

My son has an aversion to floors and wants to climb everywhere, so we set him up in his room with these medium bombs and they have been an ideal fit for his 10yo hands. The texture is the right balance of grippiness (doesn't require chalk), but not rough (doesn't tear up his hands). The customizable color options make this elite for whatever your use case is!

Great for other uses!

Well designed and built. These are slightly bigger than a baseball. I started out with the small bombs and upgraded as I improved my climb. These holds will also improve your crossfit game. I also attach these to dumbbells, kettlebells, and weight bar!
