AlterG® Pro Anti-Gravity Treadmill® for Elite Athletes

Imagine being able to reduce your athlete’s body-weight impact to as little as 20% during training, in increments as small as 1%. The AlterG® Pro Series with top-of-the-line Woodway treadmill uses patented, innovative Differential Air Pressure (DAP) technology developed by NASA to unweight your athletes with an unparalleled level of precision. Dial in your rehab or training experience by reducing body-weight impact up to 80% and open up the power of unweighted training.

The Benefits of Precision Unweighting

  • Limit downtime by training through injuries and return to sport in better condition.
  • Begin post-surgery training sooner.
  • Increase training volume while minimizing stress-related injury.
  • Utilize objective data to measure your progress.
  • Stay engaged and motivated with objective, data-driven feedback.
  • Train harder, and longer soon after injury or surgery
