    The Benefits

    Thanks to its precise unweighting technology, the AlterG Anti-Gravity Treadmill allows you to push your training and physical therapy rehabilitation further than ever before. You can:

    • Reduce gravity’s impact by selecting any weight between 20% and 100% of your body weight by 1% increments
    • Rehabilitate lower extremity injuries with less pain and less impact
    • Improve mobility, strength and safety for those with neurological conditions
    • Provide a safe way to lose weight and exercise more intensively while unweighted
    • Train without pain and reduce the stress to joints and muscles
    • Recover effectively and with less pain after training or competition

    The Technology

    AlterG’s technology was originally developed at NASA as part of an effort to help astronauts maintain fitness during prolonged space flight. AlterG combined this technology with an advanced pressure regulation system and a treadmill to produce the first anti-gravity treadmill. AlterG is the first company to use a pressurized enclosure to provide a counterforce to the person’s body weight, reducing their effective weight on the treadmill surface. The AlterG Anti-Gravity Treadmill has been cleared by the FDA as a medical device applicable for uses in rehabilitation after lower extremity injury or surgery, aerobic conditioning, weight control, gait training for neurological conditions, and strengthening and conditioning for older patients. In addition, the AlterG Anti-Gravity Treadmill has seen overwhelming adoption as a training and conditioning tool that also reduces the risk of impact-related injuries while exercising.         

    The AlterG Difference

    With its unique unweighting capabilities, the Anti-Gravity Treadmill allows you and your physical therapist to move your training and rehabilitation forward by:

    • Allowing you to walk or run with no pain while maintaining a normal gait
    • Reducing stress on joints and injured areas of your lower body
    • Giving you the confidence and ability to run or walk longer and recover faster with less pain
