AlterG Anti-Gravity Treadmill


What is the AlterG?

  • The AlterG or ‘anti-gravity treadmill’ was originally invented by Robert Whalen, a biomechanics researcher at NASA to help combat the loss of bone mass and muscle in micro-gravity.
  • In 2005, the technology was licensed to a company called AlterG.  Instead of adding weight to astronauts in space, AlterG uses the technology to take the weight off of rehab patients recovering from a variety of ailments.
  • To use it, you put on a pair of tight neoprene shorts,  step onto the treadmill inside a hole in its plastic casing, and zipper yourself in so that from the waist down, you’re encased in an airtight plastic bag.
  • The the machine uses un-weighting technology to make you feel up to 80 percent lighter!

How does the AlterG help?

  • Reduces gravity’s impact by selecting any weight between 20% and 100% of your body weight 
  • Rehabilitates lower extremity injuries with less pain and less impact
  • Improves mobility, strength and safety for those with neurological conditions
  • Provides a safe way to lose weight and exercise more intensively
  • Trains without pain and reduces the stress to joints and muscles
  • Recovers effectively and with less pain after training or competition
