Training with No Gravity Part 2

A few people asked me to write a bit more about my experience with the Alter G.  I’ve run on it 5 times now (so I’m not any sort of expert).  I do know I have not regretted a single run.  I haven’t felt pain during or after run, so I’m honestly glad I’ve started using it.  I actually think my recovery is starting to go really well (but I also feel extremely jaded because my last run was at 77% body weight).

Before last week, I had heard about an Alter G treadmill but never used it for myself.  I had seen it downstairs but never used it.  I had seen one of my elite coworkers use it but seeing someone run 5 min miles like no big deal….well you don’t stop to chat while they are doing workouts.

I honestly hadn’t even done that much research about it prior to last week. I was letting an extremely useful training tool pass by me.  After my doctor said I could use the alter G, I did more research and decided to give it a go.

I knew we had one at Haddonfield Running Company to rent and use.  Finding one would have probably been the hardest hurdle.  Life granted me a ray on sunshine though.

So last week I went in to do my 20 minutes.  I knew nothing and once again I had done very little research until about an hour prior.  70% seemed to be the optimal starting point in beginning to run post stress fracture.

You wear a pair of party pants that essentially zip you into the machine.  As it calibrates, you stand completely still with you arms crossed.  It’s a lot easier said then done.   The chamber where you will run fills with air.  The gravity almost feels as if it’s lifting you off the ground. It’s a strange and indescribable feeling. I felt like I was running in the pool but with no resistance.

After I made it through my 20 minutes completely pain free, it was more the afterwords I was worried about. The next few minutes I felt fine. I chatted with my coworkers. I drove home and felt fine afterwords. I haven’t had any extra aches, pains or problems since adding these Alter G runs. I’ve started to slowly up my body weight use from 70% body weight to 77%. My plan is to keep slowly upping my body weight until I feel good running at 95%, then I will try running outdoors.

(I’m not being payed to be injured and review an Alter G)

Questions for you:
Have you tried an Alter G?
How do you come back post injury?



  1. That thing looks super cool! I would love to run on it just to see how it feels. I’m glad that you don’t have any pain running on it and I hope the rest of your recovery goes well!

  2. That is so cool you have access to this – I think it will be a great way for you to get back to injury-free running.

  3. Your last sentence made me laugh. Hmm which makes me wonder how much someone would have to pay me to be injured…. A lot!!
    Glad it’s going well tho and I think your approach is very sensible 🙂

  4. Haha that’s funny that you pointed out that you weren’t paid to be injured and try at alter G. I wouldn’t mind being paid to use and Alter G again but no thanks to the injury part!

  5. Awesome Hollie! I have never been on one of those, but I have always wondered what it was like. You are right about the after being the big concern, with most injuries that is the time you have to be nervous about, but sounds like you are moving your body along nicely. You will be back before you know it. Glad you are able to run again 🙂

  6. LOL at your last sentence. I have always wondered what running on one is like!
