"I'm totally blown away by this thing...three times the muscle per minute of exercise."
"Love this product! I've used it with everyone from professional athletes to weekend warriors. It provides enough force/load to generate muscle mass & strength in a short amount of time. It works. There is no doubt about it." -Billy beck, world renowned human performance specialist
"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
