Running on an AntiGravity Treadmill

Running on an AntiGravity Treadmill

Since posting on Instagram about running on the anti-gravity treadmill, better known as the Alter-G, many people have asked to write about my experience on there!

The Alter-G is a great tool that I am fortunate to have access too.  You can see a full list of Alter-Gs near you or in your area.  If you’re Philadelphia or Southern New Jersey local, the one I’ve been using is it at RunningCo. Of Haddonfield.

Alter G is not paying me or sponsoring this post is anyway.

Like many runners, when I have the time I like to run outside. I’m no stranger to the Alter-G and have used it recovering from a few injuries. Injury recovery is probably the most well-known reason to use it, but it’s not the reason I’m using it now.

As I’ve mentioned, I’m busy for a few weeks and running outside is not always an option unless I want to run in midday in 90 degrees.  Since I don’t, my choices are run on a regular treadmill, run on the Alter-G or don’t run. Because I also don’t know what each day is going to bring, my training could also be all over the place.  One week, I could have time for 70 miles.  The next week, only 20.  Drastic changes in mileage would create an injury.   So, I settled on running on the Alter-G.  I’ll still get a workout in and retain muscle memory.  However, I won’t put as much stress as my body.

As I mentioned, many people use the Alter-G to run while recovering from an injury.  There are a few great articles and case studies of how elite runners have trained on the Alter-G during recovery.   Many professional runners also use the Alter-G to keep stress off their bodies, so they are less injury prone.

You can run anywhere between 20% body weight and 100% body weight.

Here are just a few benefits with the anti-gravity treadmill for runners:

  • Physical therapy following an injury to a lower extremity (like the feet or legs)
  • Prolong your running career by building leg strength without the full impact on your body
  • Maintain and develop cardiovascular fitness while injured or away from sports.
  • Run longer and recover faster with less pain
  • Gradually progress and easily adjust the intensity of your workout
  • Change your running form without becoming more injury prone.

So What Exactly Happens?

You put on a pair of specialty pants, step into the Alter-G and allow it to calibrate to your body weight.  From there you can adjust to how much weight you would like to run at.  You can run anywhere from 20% body weight to 100%.

Right now, I feel between 60-70% is a good number for me.  After the machine calibrates, you just run.  You can do anything that you do on a normal treadmill including hills or speed.  I have seen several local elite runners do workouts on it and some people (like myself) just prefer to Netflix and run.

So Why Have I Chosen to Go This Route This Summer?

It’s not a secret I’m injury prone.  Due to my form, I stress my metatarsals more than the average person.  When my training becomes inconsistent, I get injured. As I mentioned, since I am busy this summer, I can’t guarantee I’ll be able to consistently run.

That isn’t because I don’t want to run but because I don’t have the time.  For the last couple of weeks, I’ve been out of the house from 6 am-7 pm.  Sometimes I have a couple of empty hours in the middle of the day, but at that point, it’s 90+ degrees.  I would prefer to run inside anyways.  Thinking out loud, it just makes the most sense right now to use the Alter-G and not overly stress my body.

Incase you missed Monday’s training log, I posted a short video about going through the process.  (And yes, I do make random comments like that frequently)…

  1. I have never heard of these treadmills! I wish I would have though five years ago when I was recovering from an injury.

  2. I’m in the Haddonfield area and I am recovering from an IT issue. Would I be able to you the Anti-gravity treadmill?

    1. Robin,

      You would be able too. It is not my Alter-G, but the RunningCo. of Haddonfield! You can definitely give them a call or stop in to schedule a time slot there!

  3. I tried this maybe 3 or 4 years ago when my knee was acting up and it was such a cool feeling! Unfortunately with this injury it made me want to over extend my leg, so it wasn’t great. I need to try it again though, so fun to make your legs fly

  4. That’s awesome you have access to an Alter g! My chiro just sold his, which is bad timing as I”m trying to come back from injury and would have used it a lot. But I agree, it’s perfect for injury prone runners and to get those extra miles in without the impact.

  5. My local sports chiro has an Alter-G in his office that he lets his patients run on, which is amazing! I’ve run on it a couple of times. It’s definitely an odd sensation at first, but I enjoyed running on it. I remember feeling super heavy on the regular treadmill after running on the Alter-G though! LOL.
