The Ironman Gravity 4000 is an extremely sturdy table with a max weight capacity of 350 lbs.
The table is well built and comfortable. It feels sturdy and secure while you are using it – the table doesn’t shake and the inversion is smooth.
Using the table, you can feel the thought they put into the design. Easy to adjust height, comfortable ankle restraints, perfectly placed handlebars. Everything about this table is easy to use and works well.
The only down sides I could find are the weight and bulk. Because it’s such a sturdy inversion table, it needs to be heavy and bulky. It does fold up for storage, but even folded up it’s still quite bulky.
What you are doing when you buy this inversion table is trading storability for stability. And stability is what this table is all about.
I think it’s well worth the price they are charging of approximately $200. I have no problem recommending the Ironman Gravity 4000. All things considered, it’s probably the best inversion table out on the market.

Common questions about the Ironman Gravity 4000
Here’s a list of commonly asked questions. I hope they’ll help you to decide whether the Ironman Gravity 4000 inversion table is right for you.
Does it fully invert?
Yes, the table allows for full inversion. It has an adjustable strap that allows for full inversion or more limited inversion. If it’s your first time using an inversion table I recommend working your way up slowly to full inversion.
Can I do sit-ups while inverted?
This inversion table wasn’t designed to do sit-ups on. There is no locking mechanism that keeps you inverted, just the strap that adjusts your level of inversion. So, as you do a sit up, there is a good chance the table will swing back up.
Is the table adjustable for height?
Yes, the table can be adjusted for people 6’6” to 4’9” (198 cm – 145 cm). The height adjustment is super easy to use and lets you adjust the center of gravity of the table to your specific height. You could probably stretch the height limits an inch or two shorter or taller and still get good results.
Is it easy to fold up and store away?
Somewhat. The Ironman Gravity 4000 table comes apart and folds up quite easily but the backrest and legs are relatively heavy. The whole inversion table is about 60 lbs. When the inversion table is disassembled and the legs are folded up it’s still a little bulky. You probably won’t want to disassemble and reassemble the inversion table every day. Really, it’s bulk and weight are the only downsides of the Ironman Gravity 4000 inversion table. You can see it being disassembled and folded up for storage in the video above this section.
What is the weight limit?
The weight limit is 350 lbs. I’m about 200 lbs and this table did not shake at all when I was on it. It felt very sturdy and secure. Which is pretty important when you are hanging upside down!
How comfortable are the ankle restraints?
Very comfortable. This was one of the best parts of using this inversion table. The ankle restraints are the perfect mix of comfortable while still feeling secure. I had no problems at all with the ankle restraints while using the Ironman 4000.
Is the lumbar support adjustable/removable?
Yes, the lumbar support pillow can be easily slid up or down. It can also be easily removed or put back on.
Does it have a warranty?
Yes, it has a 1-year structural frame warranty and a 90-day warranty on all the other parts. I’ve included a picture of the warranty page below. The warranty is in the back of the owner’s manual, I’ve scanned the whole manual and there’s a link to it below. But here’s a screenshot of just the warranty:

Assembling the Ironman Gravity 4000 inversion table
As you can see from the video the inversion table is fairly easy to put together. Here is a close up of the assembly tool you’ll be using:
The user manual for the Ironman Gravity 4000 does a great job of clearly explaining how to put the table together and how to use the table properly.
Some things you’ll want to watch out for when assembling the Ironman 4000:
Grip both of pivot arms and squeeze them in while moving the backrest. That will stop them from sliding around in the bracket while you are moving the backrest. Also, once you’ve got one pivot arm secured to the legs, you’ll probably need to push on the legs to get the other pivot arm to slide into its groove.
Don’t do what I did and put the backrest the wrong side around. You’ll see what I mean if you watch the video.
Make sure the ankle cuffs are securely attached. There is a tab on the cuff that fits into a groove on the bar.
Don’t forget to screw down the safety lock on the adjustable foot rest.
Make sure to put the two washers and lock nut in the right place when attaching the handlebars.
Really though, if you follow the instruction manual closely you’ll have no problems assembling the chair.
Using the Ironman Gravity 4000
Using the Ironman 4000 is an absolute joy once you have it all set up. You can see a video of me using it at the top of this article. But I’ll walk you through the steps with some pictures in case you aren’t in the mood to watch a video.
Just a heads-up, you might want to wait a while after you eat to use an inversion table. If you do invert right after eating, it can cause some nausea.
Step one, adjust the height. You can do this easily just by pulling the pin on the back of the backrest and sliding the foot rest in or out. Make sure the pin is locked in once you set the height and tighten the screw on the back of the backrest to lock the foot rest in place.
Next, adjust the strap to your desired level of inversion. I definitely recommend starting out with a small amount of inversion and then working your way up to full inversion.
After that, get on the table by stepping onto the foot rests and locking the ankle restraints in place. Lock down the ankle restraints down as tightly as possible, but not so much that they are painful. It’s okay if your feet leave the foot rest when you invert, the ankle restraints will hold you. You’ll also want to adjust or remove the lumbar support pillow depending on your preference.
Next up, inversion. You’ll lean back on the backrest with your arms by your side. As you slowly raise your arms the table should slowly start leaning backward. If nothing happens or if you start leaning backward as soon as you lay back on the backrest, you should adjust the height until your center of gravity is right in the middle of the base. You should be able to invert just by slowly raising your hands.
Once you’re inverted, you’ll want to stay that way for a short amount of time in the beginning until your body gets used to inversion. The manual also recommends some light movement/exercise while you are inverted to keep the blood circulating.
Lastly, come up slowly. You’ll get light-headed if you come up too quickly. You can return to standing by lowering your arms slowly to your side or using the handlebars to help you up. Take it slow.
There’s more information about how to properly use the Ironman Gravity 4000 in the owner’s manual and you can also watch the video at the top of the article to see me using it.
Folding up and storing the Ironman Gravity 4000
You can watch me folding up and getting the inversion table ready for storage in the video at the top of this article.
Basically what you will do is unhook the strap. Then you’ll grab the two pivot arms on the backrest and work the backrest free of the base. To make it a little easier you can also remove the foot rest by loosening the screw on the back, pulling the pin, and then sliding the foot rest out. After you’ve removed the backrest you can fold up the base and remove the pivot arms from the backrest. Then you can store the pieces however you would like.

*People who have a coronary illness, hypertension, eye problems (glaucoma, infection, etc.) or are pregnant are at high risk for problems identified with invasion therapy and should consult with their medical specialists first. Such individuals, with their physician’s approval, would need to advance gradually, beginning at light levels of therapy.
