We believe that truly amazing things happen when people reach their goals—When what starts out as a vision becomes a personal victory. Because from that point on, all future victories feel inevitable. That’s why we want to empower people to be their greatest self in and out of the water.
FOR ALL FUTURE VICTORIES.
Founded in 2018, GMX7 exists to change the world of swimming by empowering swimmers with the best aquatic resistance training device ever created. GMX7 founder, David McCagg, is a 7-time Gold Medalist, former World Record holder and winner of multiple National Championships.
After retiring from a successful career in Real Estate Development, David decided to reenter the world of swimming. Thinking back to his time training under elite Olympic coaches, he knew his success and the success of others boiled down to one thing: how they trained in the water. Revitalized by this, his passion for the sport was more focused than ever: to forever change how athletes approached training.
We understand new training tools can be daunting for coaches and athletes, but we are here to help! GMX7 has incorporated strength and eﬃciencies into Aquatic Resistance Training that has never been done before, providing a guide for maintaining the correct stroke technique and body position for all 4 strokes. The X1-PRO provides unlimited options to resistance training, including breakouts, sprints, distance, 50’s, 100’s, 200’s etc. Any sets, or combination of sets, at any distance from zero to immovable resistance. If you, as a coach or athlete, can think it, you can train it with resistance. With no limitations, coaches are finding unique ways to implement the X1-PRO not only in power training, but endurance training, stroke drills, hip rotation alignment and countless more drills every day.
GMX7 has been fortunate enough to have insights from some of the greatest coaches in swimming including Greg Troy, Mark Schubert, Ira Klein, and David Marsh. After extensive testing with the X1-PRO among the most elite athletes in the world including Ryan Lochte, Caleb Dressel and countless other pro and age group swimmers, we are confident we can compile training programs tailored to you or your swimmers exact needs.
