Let Science Drive Growth

Many athletes looking to maximize hypertrophy are turning to flywheel training for its unique scientifically-backed advantages over traditional weightlifting methods.

With Exxentric devices, you can train smarter with variable resistance, eccentric overload, and the freedom to customize exercises for optimal hypertrophy results.

Train Better. Grow Better.

Discover Why Athletes Choose Flywheel Training.
  • Eccentric Overload

    Consistently shown to elevate hypertrophy – Exxentric devices let you easily and safely integrate eccentric overload in your hypertrophy training.
  • Variable Resistance

    Self-adjusting variable resistance means perfect load at every angle and muscle length – creating perfect reps from start to finish!
  • Exercise Selection

    Offering exercises like harness squats – Exxentric devices let you train heavy compound movements with minimized axial loading and improved muscle targeting.
  • Multi-Directional Resistance

    Unlike gravity, flywheel resistance isn’t limited to one vector – opening up a wide range of technique modifications for better stretch, pump, and mind-muscle connection.
