Who SHOULD use the Alter-G?

AlterG Anti-Gravity TreadmillAthletes, weekend warriors, post surgery, hip and knee replacements and those just looking to preserve their joints can benefit from the AlterG technology.  If the runner or athlete is injured and running is painful typically these athletes are sidelined or benched.  For long distance runners this usually means they will not achieve their goal.  Now, with the AlterG technology injured runners and athletes can continue to run and maintain their cardiovascular fitness and muscle mass while at the same time return to sport sooner and less de-conditioned.


  • Allows adjustable impact while walking or running.  We simply adjust the AlterG to take a percent of your body weight away thus making you lighter with the same associated percent decrease taken away from your muscles, bones and joints  You will be amazed as the pain just…disappears!

  • Allows for gradual progression of exercise.  Some injuries or joint replacements can mean a long road to recovery…not anymore!  With the AlterG we can start you on the road to recovery sooner and scientifically progress you forward by gradually adding a percent of your body weight back as your body strengthens and adapts.

  • Minimizes impact and torsion forces that can lead to injury.  Runners who want to increase their mileage but minimize their risk of injury can now do so with the AlterG technology.  Even older runners who have decreased their mileage or stopped running altogether can run pain-free on the AlterG!

How does the Alter-G work?

Using NASA patented Differential Air Pressure technology and clinically supervised by a Doctor, the AlterG “unweights” you by as much as 80% of your current body weight (adjustable in 1% increments). This uniquely adjustable process allows the user to walk or run pain free in a comfortable and stable environment.


  • A computer precisely reduces ground reaction forces 1% at a time

  • Decreases discomfort and encourages normal biomechanics

  • Generates a safe and stable environment to work on technique

  • Allows for increase training volume with less impact and ground reaction forces

Can I use the same equipment the pros use…

but at a fraction of the cost?

AlterG Anti-Gravity TreadmillThe AlterG has revolutionized rehabilitation techniques in walking and running sports. Elite athletes and runners have benefited from this technology for years and now you can too!  From world class marathoners to the LA Lakers, the Chicago Bears to the Boston Red Sox, trainers and sports medicine professionals use the AlterG to get out-of-this-world results.  Nothing is like the AlterG.  Pool running, bungee cords and other devices used to “unweight” a person are things of the past.  The AlterG does not simulate walking and running, it is walking and running, you just weigh less.

Individual sessions and Packages are available in 50-minute increments.  Even “Double Sessions/Packages” in 100-minute increments are available for those that want to get in a longer training run, rehabilitate quicker, or travel from a distance to use the Alter-G.
