"For strength training outside of the water, I have tried weights, kettle bells and TRX. X3 is a far superior exercise system to anything I have experienced over many years of competitive swimming and coaching. X3 challenges my muscles more effectively and efficiently resulting more strength and faster times in the water! Athletes that use X3 will have an advantage over those who don’t."
-Andrea Vuturo Certified ASCA swim coach and open water swimmer

-Billy beck, world renowned human performance specialist
“The central nervous system does not know the difference between rubber, a brick wall, or iron. X3 is the best way to lift heavy and be injury free.”
-Phil Hernon, Mr. USA 1995
“X3 has given me an edge with more explosive strength and speed.”
