The AlterG Anti-Gravity Treadmill delivers physical rehab and training benefits you can’t get any other way.  Combining patented NASA Differential Air Pressure technology, an intuitive touchscreen interface, real-time gait analytics, and live video monitoring, enables body weight supported walking, running, and closed kinetic chain exercises like never before.  The AlterG uses air to comfortably and precisely unweight the user to as little as 20% of body weight to reduce impact and gravitational forces without compromising natural biomechanics.
