A Stronger Basketball Player – Is a Better Basketball Player

By harnessing the endless and variable rotational energy of a flywheel – Exxentric devices offer resistance that is more effective for explosive jump training, a movement freedom with greater carryover to game-specific action, and a loading profile that is safer and more intuitive for basketball athletes.

By letting you adjust the angle of resistance and eccentrically overload sport-specific actions -Eccentric flywheel let you replicate and prepare for on-court demands. Directly load lateral changes of direction, overload the amortization phase for improved and safer force transfer, and explosively train harness and single-leg squat variations for vertical jump power.

  • Explosive Power

    With variable resistance that lets you train with maximal explosive power on every rep – Exxentric devices put inches on your vertical, not just pounds on your squat.
  • Sport-Specific Lateral Training

    Multi-directional resistance and specialty training accessories let you train a wide range of loaded lateral movements for game-defining change of direction speed.
  • Eccentric and Amortization

    Harness eccentric overload to supercharge the eccentric and amortization phase and blow up your vertical jump, change of direction speed, and overall power production.
  • Prevent Injury

    Prepare your joint and tendons for any landing, change of direction, or misstep with scientifically-proven eccentric overload protocols.
