Despite COVID, Tampa Company Changing Competitive Swim Industry as Olympians Flock To Use Their New Trainer


A revolutionary new device manufactured by St. Petersburg-based GMX7 is allowing competitive swimmers across the world to add resistance to their swim training regimen in a safe, effective, portable and easy-to-use manner.

From reigning 100-meter butterfly world-record holder and 2-time Olympic gold medalist Caeleb Dressel, to 6-time Olympic gold medalist Ryan Lochte, who holds the world record for the 200-meter individual medley, the X1-PRO, assembled in the USA by GMX7, is quickly becoming the favorite new competitive swimming training device on the market today.

The X1-PRO is a small 6-inch long device with adjustable resistance that weighs less than 5 pounds and clips into the end-point connections for a pool’s lane lines. The X1-PRO is connected to the swimmer via a leash and travels on a line back and forth up to 50 meters in length.

Currently, more than 75 anticipated Olympians from 10 countries across the world are training on the X1-PRO in hopes of qualifying for the Tokyo Olympics. Additionally, several collegiate level athletic programs, including the Florida Gators swim team, are also currently training on the device.

“We really wanted a device that would be easy to use, fit inside a backpack and deliver unprecedented results, and I’m proud to say we blew those expectations out of the water,” said David McCagg, founder and CEO of GMX7. “To see elite athletes embracing our device worldwide is truly rewarding.”

Development of the X1-PRO began in 2018, and it was tested extensively at the University of Florida prior to becoming available to the general public earlier this year.
