In this review, I will take a look at the Ironman Gravity Inversion Table 4000.  I will discuss the features and benefits of this inversion table, and what you can expect if you were to purchase one. If you are in the market for a heavy-duty inversion table, I encourage you to keep reading.

With so many inversion tables available today it can be hard to find just the right one. I have used different inversion tables over the years, and my goal is to shed some light on this model from Ironman.

Ironman 4000 Inversion Table

How do inversion tables work?

Inversion tables help to elongate the spine and take pressure off of the discs.  By inverting, the discs are able to recover and rehydrate.

I use an inversion table as I have chronic sciatica and inverting really helps me out.  Some people have tight muscles, or a herniated disc, just a few of the conditions an inversion table can help with.

It’s best to check with your doctor to make sure you are fit to use an inversion table, as people with certain medical conditions should not invert.

Ironman Gravity 4000 Inversion Table


The Ironman Gravity 4000 support users up to 350 pounds, which is definitely more than most inversion tables on the market today.  People come in all shapes and sizes, so it’s nice to know that this table can be used by a wide variety of body types.

The table is made from tubular steel and is very sturdy.  There are protective, rubber non-skid floor stabilizers, on the bottom of the inversion table which will help protect your floors.  These non-skid stabilizers will also help to keep the table firmly in place when you are upside down.

Ankle locking system

To me, this is one of the most essential parts of any inversion table.  After all, you will literally be hanging upside down by your ankles.  You need a comfortable solution that will protect your ankles, feet and distribute your weight evenly.

This unit has ergonomic ankle cushions that cup the front and backside and provide a secure and comfortable fit.  Most people have said the padding is adequate.  There is no pinch point pressure while you are inverted.

The Palm Activated ratchet locking system

Another super important feature is the extended-release handle.  This handle provides an easy way to release (or escape) from the table when you are finished.  I wish more inversion tables had a longer handle release.

This extended handle makes it so you don’t have to bend over very far to release yourself.  From experience, I can tell you this feature is invaluable. I have been in situations, recovering from an injury, where I literally couldn’t bend over, so the extended handle is a must in my opinion.

Also, the ratchet locking system allows you to get just the right fit for your ankles, not to tight and not too loose.  Inverting with the ankle lock too tight is not fun, and if it’s too loose, you feel like you are going to end up on the floor.

User height adjustment

The adjustable user height is pretty easy to set up here as well.  You want the table to rotate in and out of inversion easily so getting this right is important.  You should be able to return to the upright position, almost effortlessly by moving your arms.  You shouldn’t have to strain to return to the upright position.

There are preset height settings on the unit, and all you do is pull the pin and slide the bar to select your height.  Sometimes, depending on your center of gravity, or if you are between heights, you may have to adjust the setting slightly.

For instance, if you are 6’0” and the table is difficult to rotate up and down, you may need to try the 6’1” setting.  You can play with it and make sure you get it set up correctly.

Most people will just need to set the height accordingly and go with that.

Inversion table angle adjustment

There are two methods that inversion tables are equipped with to set the angle you are going to invert at.  One uses a preset push pin mechanism, and the other is a tether strap.  I will explain both of these designs and explain which one I think is better.

A table with a push pin mechanism has preset angles, like 15, 30, 45, 60 degrees, etc. These preset options make choosing your inversion angle very easy but do have limitations.  You are restricted to these preset angles, and if you need a different angle you are out of luck. For most people this may be fine. I will explain in more detail how the tether strap is superior in my opinion.

This IRONMAN unit employs the tether strap method.  I favor the tether strap as you can literally set the angle anywhere you want.  You are not limited to the preset angles.

When I was recovering from a back injury in late 2015, early 2016 I had to start at a very shallow angle, like 15 degrees.  Due to the nature of my injury, I was only able to make smaller adjustments, like 5-degree adjustments, to my inversion angle. The preset inversion angle design would not have worked for me in my recovery.  Given this, a tether strap is a must in my opinion. I prefer the customization of the tether strap style.


The Ironman Gravity 4000 has a thick memory foam pad which is really easy on the back.  There is an included lumbar support for your lower back, should you decide to use that as well. The bed is wide and sturdy, and the table can support up to 350 pounds. I have used this particular model and can confirm that it is comfortable to lay on. The backrest is easy to clean also.


Ah, the fun part, you will need to assemble the inversion table. You can follow my pointers for assembly here. I highly recommend you have someone available to help you.

Sure, you can build it all by yourself, but it will take longer and probably be more frustrating.  Inversion tables are awkwardly shaped and can be heavy, making them difficult to assemble and move.

If you are nursing a back injury, the last thing you need to be doing is trying to maneuver a heavy piece of equipment (been there, done that), that is why I recommend that some help you.

If you really don’t want to put it together yourself, assembly is available for an extra charge’


Okay, so they always promote how these inversion tables fold up, and you can store them away.  Well based on my experience, it’s not that easy.  If you are using an inversion table to recover from a back injury, or you are in pain, the last thing you really want to do is haul a 75 pound, awkwardly shaped inversion table very far.

I find it is easier to keep it in the room I am using it, like an office, spare room, or basement and then yes, you can fold it up, but just lean it against the wall.  These tables are difficult to store underneath a bed, or in a closet. Sure, it’s not the prettiest thing to have in the corner, but it also serves as a great place to hang clothes.

Final Recommendation: Ironman Gravity 4000 Inversion Table

I hope you have enjoyed this inversion table review. You didn’t know there was so much to consider with an inversion table right?

This inversion table is well built and offers a lot of functionality. I really think this table is a good value, for the price.  You can find similar units that are priced higher than this and will provide the same functionality.


  • Budget-friendly inversion table
  • Supports up to 350 pounds
  • Extended handle ankle lock system means less bending over
  • Tons of positive customer reviews


  • The memory foam back may cause some people to get a sweaty back
  • It’s really heavy to try to move around

The table comes with extended handlebars, which are helpful for returning upright.  Although if you have the table set up correctly for your height, you really shouldn’t need to use the handles.

You can fully invert with this table.  Whether that is 90 degrees or 180 degrees, I am still not sure what to call it, but either way, you can be completely 100% upside down.

I will tell you from experience that inverting can take some getting used to.  I recommend that you start off with a shallow angle and work your way up (or down depending on your perspective) from there.  As you get more comfortable and confident, inverting is easy.  I currently use a 60-degree angle and find that is a great angle for me.

I definitely recommend wearing shoes (athletic) and socks, as this is really big help.  I have tried to skip this step, and I always regret it.  The padding is only so good, and when your body weight is pulling against your feet and ankles, it’s really nice to have shoes on.  I promise you won’t regret wearing shoes.

  1. The Ironman Gravity table looks like an important piece of exercise equipment especially for anyone who does regular healthy exercise but has some back problems. There is nothing worse than doing an exercise and stopping because of your back giving out. Thanks for sharing this post, it’s very informative. Do you know if this model is available in the UK?

    • Thanks for your comment, Andrew. Unfortunately, this model is not available in the UK, but there are other models that are. I agree with you, back problems can make working out challenging, but one of the best ways to beat back problems is exercise. Please let me know if you have any more questions!

  2. I love this idea. Even though you say it’s heavy, this hardly seems like an item you’d need to move often, which is a plus!

    • If you have the space for it, you are correct, you shouldn’t have to move it often. Some people just don’t want to have it out where people can see it, in that case, they want to move it. Of course, the company that makes the equipment wants to promote it as something that can be stowed away, but it’s not so simple. Thanks for stopping by, I appreciate your comment.

  3. Hey Steve, I’ve been thinking about an inversion table. I’m beginning to have back issues, and it’s a family issue as well. You’re right there are so many but your article gives me a good starting point. Thanks.

  4. I really love the detailed and informative information about Ironman Gravity Inversion Table 4000 because I had been looking for such an item.
    I love that it is budget-friendly as a unit.
    The only thing I am worried about is the fact that it is heavy to carry around and needs to be in a spare room of which I do not have currently.
    Thanx for the great review.

    • Yes, the one problem with these units is if you are limited on space and want to store it away, that is not always the easiest thing to do. Like I mentioned in the review, I lean mine against the wall when I am done with it, that at least helps to get it somewhat out of the way. I agree it’s a budget-friendly unit and provides a lot of value. Thanks for your comment, I appreciate it.

  5. Since I don’t plan to be moving this ironman gravity inversion table 4000 everywhere, this is just perfect for me. It was just prescribed to me that I should try to make use of an inversion table but I was clueless as to the one I should buy but having seen this written here. I am more than happy about how you have helped to limit my search. Thank you so much for sharing this. I love virtually everything about this especially the weight capacity that it can take

    • Thank you for your comment, I appreciate it.  I am glad this review helped you. The weight capacity this table offers is better than most of the other ones out there.  Let me know if you have any questions.

  6. This inversion table looks like the very real deal. I have seen quite a number of people talk about inversion tables but I have not seen anyone talk about it so indeptly. I think that the product is really cool especially for those with back pain. I just remembered that my dad complained about having some issues with his back. I think this Ironman inversion table will be very helpful for my dad. Since it is affordable, I will show him to see if he’ll like to try it out.

  7. I found this review very helpful. I have back problems and I think that I can benefit from this table a lot. What I like about it is its special design and immobility. Price is pretty affordable compared to its features which is also a big plus. I will definitely get one for me, it looks promising.

  8. As a guy who recently pulled a back muscle and went through 30 days of limited mobility, this looks like a fantastic product.

    I can see where hanging upside down would take pressure off of certain areas of the back and help to decompress the spin.  Looks like this product might also help prevent spinal decompression.  Just have a couple of questions.

    How long do you spend in your inversion table sessions?  And, do you recommend it on a daily basis?  Finally do you find that using this table on a regular basis helps to prevent flair ups of back pain?  I’ve had two major episodes of back problems in the last 4 years and would really be interested in a regimen that would help prevent a third.



    • Hi Ralph, thanks for your comment.  Sorry to hear about your back muscle, I hope you are feeling better.

      Check out my post here about the benefits of inversion. 

      As for your questions, I use my inversion table regularly, which means at least 5 days per week, oftentimes every day. The exception is when I am on vacation.  I am still trying to figure out a portable option, I think that would be an amazing idea.

      I invert for about 4-5 minutes each day and I absolutely notice a difference in my back when I do not invert regularly.  I believe that is where the benefit comes from, inverting regularly.  

      I liken inverting to going to the gym. If you work out consistently, your fitness level will improve and you can get stronger. Once you reach a certain fitness level, you can maintain your gains. If you stop working out, you will lose your gains. 

      When I use my inversion table consistently, I feel less pain. I reached a certain point with inverting and it helped me get over an injury.  Now I maintain by inverting daily.  I hope this helps you.

      Please let me know if you have any more questions, I am happy to help.

  9. Hi Steve, the Ironman Gravity Inversion Table 4000 looks like a great inversion table to help maintain a strong body. From my impression, it does seem like an inversion table is meant for older people with back problems. What are your opinions on using it for a sixteen-year-old athlete? Does it help athletes improve performance too?

    • Hi Kevin, thank you for stopping by.  Inversion tables are not just for old people, I can assure you.  I have been using an inversion table for years, but I might be considered old LOL.

      As for young people using an inversion table, definitely check with your doctor first.  If a young person has back problems, an inversion table might be a great option.  

      Some people do use an inversion table for athletic performance, and I know people who use them to do sit-ups for improved core strength. I strictly use my inversion table to relieve back pain.

      I hope this answers your questions, please let me know if you have any further questions.  Thanks for your comment, I appreciate it.

  10. Such wonderful equipment to help with back problems, although I don’t know much about sciatica, but having a device that can help with any health issue is one thing that makes me really glad. Some times using drug isn’t always the best solution to a particular health problem. Seeing the usefulness of this device and its quality, its something I’ll love to recommend to anyone. But I wouldn’t mind if you share more light on sciatica. Thank you.

    • Hello Benson, thank you for your comment.  Feel free to check out my post here for more information on sciatica.  Basically, sciatica is pain that travels along the sciatic nerve.  Many times a herniated disc will cause pain to travel along the sciatic nerve and this pain is referred to as sciatica.

      I agree with you about finding alternative solutions to taking drugs for pain relief.  Using an inversion table has worked well for me.  Thanks again for stopping by, I appreciate it.  Let me know if you have any questions.

  11. Great tips you have shared here concerning the Ironman Gravity inversion table 4000. Left to me, there’s nothing else I can talk about here that you have not highlighted to be present in this product. Thank you so much for sharing this and if I ever see anyone in need of this, I will share it out to them.
