Controlled Power Creates Speed

GMX7 helps competitive swimmers, triathletes, and open water athletes build propulsion, efficiency, and immediate stroke correction directly within the swim stroke through Precision Aquatic Resistance Training.

Train smarter. Race stronger.

Built For Every Type Of Swimmer

GMX7 training systems are designed to develop propulsion, controlled power, and stroke efficiency across every level of swimming performance. Whether you’re racing open water, competing in triathlon, or training in the competitive pool environment, GMX7 helps athletes build strength where it matters most, in the water.

COMPETITIVE SWIMMING

Train all four strokes with immediate stroke feedback, propulsion development, and precision resistance that reinforces proper mechanics.

INSTANT STROKE CORRECTION

Most swim tools can show you what’s wrong after the stroke. GMX7 helps athletes feel the correction during the stroke itself. The patented resistance and guide system immediately exposes stroke inefficiencies by reinforcing:

  • Stronger water catch
  • Improved front-end positioning
  • Full stroke completion
  • Controlled propulsion

When athletes can feel the correction instantly, change happens faster. That’s what makes GMX7 different.
