Synergy Climbing and Ninja
Chattanooga, TN

Specs: This new facility is a revamped and expanded version of the Tennessee Bouldering Authority, a popular Chattanooga gym that has been in existence since the year 2000 with 3,000-square-feet of “indoor rock climbing walls and dedicated training space.”

Synergy Climbing and Ninja is a collaborative effort between legendary climber Lisa Rands and American Ninja Warrior champion Isaac Caldiero. As the gym transitions from being Tennessee Bouldering Authority (TBA) to Synergy, it will “preserve TBA’s original character and dedicated training space.” In fact, a “TBA training zone” will be modeled after the original TBA space to provide climbers with a familiar climbing area and training boards. The facility will also feature a ninja obstacle zone designed by Caldiero, a fitness area, yoga room and cafe.

In Their Words: “We’re really excited to team up with TBA, Chattanooga’s original and most respected climbing gym. We’ll have a bigger space but preserve the awesome routesetting and sense of community that makes TBA such a great place to train. It’s also amazing to work with our long-time friend, Isaac Caldiero, to bring his vision of an authentic ninja gym to our home city.”
