The Tenacity Coaches

If you’ve ever watched American Ninja Warrior, that level of athleticism can seem unattainable. Lights. Cameras. High flying action. Even beginning to train like those athletes looks impossible. In fact, when Ninja Nicole Griffin told her friends she was going to start training, they rolled their eyes and only offered two words:

“Good luck.”

Four seasons on the national stage of American Ninja Warrior later, no one’s rolling their eyes anymore. Now she owns Tenacity Training, western Kentucky’s first Ninja Warrior training, bouldering and fitness center.

Ninja Nicole grew up rock climbing, bouldering and staying active however she could. While going after a degree in Physical Education, she was able to convince her stepdad to build a full-sized rock wall of her own design in the family barn.

That’s right. A whole rock wall. 

A year later, Nicole caught an episode of American Ninja Warrior and she knew she had to go after it. Before long, her stepdad had a few new projects: a peg board and a set of monkey bars, alongside the rock wall in the barn. 

At the time, making it to American Ninja Warrior seemed like a longshot. Since then, not only has Nicole earned the title of ‘ninja,’ but she also coaches America’s next generation of athletes. 

Today, there’s history in the bones of Tenacity Training: the current bouldering wall is made of the rock wall she designed for her family barn; the peg board is made of recycled parts of her old jungle gym.

And just like Nicole built the gym from a rock wall in an old barn, we’re dedicated to building our students into better versions of themselves – facing fears, finding their inner athlete and conquering all, one obstacle at a time. 

Are you or your kids ready to join the Tenacity Family? Let’s get after it.
