Grip ball 3''


Obstacle racers, climbers, and Cross-Fit competitors are always looking for closed kinetic chain exercises. Pull-ups can provide this, but can only take your training so far. In order to strengthen muscles needed in these sports, co-contraction of the push/pull muscles is necessary to create a working system that will protect you from injury, as well as make your endeavours a success.

The F5 3” Ninja Ball provides an extra challenge to your pull ups, working muscles in the forearms, trapezius, deltoids, etc. to create a complex system of strength. These grip balls are the first step in becoming a real ninja warrior, a stronger climber, or prepare you for the Cross-Fit Games!
