These 3-inch rock-climbing cannonball bombs are an incredible tool for power training and extreme grip strength. Work alternate-grip and rotating-grip pull-ups. Switch from pull-ups to chin-ups to biceps-pull-up without stopping. The naturally ergonomic design allows for open-handed training; grip over the top or pinch around the sides for increasing thumb strength.
These types of grips are often seen on American Ninja Warrior and other extreme obstacle courses. Compatible with Slackers Ninja Line. Weatherproof textured sealant makes them great for use outdoors too!

Hang from nylon webbing or rope from pull up bar, swing set, monkey bars, rafters, tree, or anything else that will support the weight.

Please remain within your comfort level when training to prevent injury.
