Our Story

Core 3 is an exciting new fitness concept scheduled to open in January 2015 in Hanley Industrial Court.  Core 3 combines three cutting edge fitness modalities of SURFSET® ‘land based’ surfing, RealRyder cycling and TRX suspension training to create a fun workout experience that is totally new to St. Louis.

The idea for core 3 was born when Cari Benz Allen, a long time marathoner, triathlete and fitness instructor, visited Costa Rica  and tried SURFSET®.  She instantly fell in love with not only the workout but the ‘experience’ that the session created.  SURFSET® is a full body approach to fitness inspired by one of the world’s most athletic sports, surfing!

 As soon as Cari returned home, she ordered a board and began practice teaching out of her basement.  After seeing the excitement from others, she knew this was something St. Louis would LOVE.  She also noticed that the amazing core strengthening benefits of surfing could be complimented by other athletic modalities of Cycling and Suspension training so she added RealRyder cycling and TRX to the mix. 

 RealRyder® Bikes were created to be the best indoor bike on the planet – one that incorporates the fun and freedom that a real bike offers. Invented by a competitive cyclist who was seeking a more effective way to train indoors.  The Difference:  The bike frame and headset allow you to lean, turn, steer and balance enabling riders to get the great workout they are used to from cycling classes with the added bonus of core strengthening!

The TRX Suspension Trainer is the original, best-in-class workout system that leverages gravity and bodyweight to perform exercises. The TRX suspension Trainer delivers a fast, effective total-body workout that helps build a rock-solid core and increases muscular endurance. 

We can't wait to see you in our studio!  

Peace.Love.Core
