ABOUT GMX7
THE X1-PRO

Have you ever tried fitting a power tower in your back pocket? The X1-PRO is lightweight and compact enough that it fits easily in your backpack, so you can travel with it wherever your swimming takes you. We are tired of parachutes (limited adjustment options for resistance), heavy water belts (that travel nowhere), and stretch cords that sometimes break. That’s why we decided to challenge the resistance industry and create the X1-PRO!
The X1-PRO is an innovative aquatic resistance training device designed with swimmers of all levels in mind. Stepping into modern technology, the patent pending X1-PRO provides smooth, bidirectional resistance, allowing the swimmer to train with adjustable resistance through limitless workout options. Additionally, the device’s constant resistance provides instant self-correction of technique, improving stroke efficiency. Try this revolutionary device yourself, and see the endless possibilities!

Sergio Lopez - Virginia Tech - Men’s and Women’s Head Coach and Olympic Coach
“The X1-PRO is an essential resistance training tool that every coach should have and use with their swimmers. It is very simple to set up, easy to maintain and barely uses any storage space. You can use it every day to work on developing power/speed on the start, turns, underwaters and breakouts. Also a great tool to use with low resistance to work on technique correction and stroke awareness. The fact that the X1-PRO is so portable makes it an essential piece of equipment to take to training camps and competitions to be able to keep working in developing and improving the stroke technique and conditioning.”
THE X1-PRO
“Resistance like no athlete has ever experienced.”
