Teeter FitSpine X1 vs. X3 Inversion Table Review

In this review, I am going to compare the Teeter FitSpine X1 vs. X3 inversion tables.  These two models offer some similar features as well as a few pretty significant differences. We will cover all of that in this review. If you are in the market for an excellent inversion table, I encourage you to keep reading and find out which model is best for you.

I own a Teeter inversion table and use it regularly since I have a long history of back problems.  Unfortunately, I am well versed in using an inversion table, and I can point out why I think Teeter offers such great value with their products.

With that said, let’s get into this review.

Teeter FitSpine X1 vs. X3


The X1 and X3 inversion tables share the FlexTech backrest which is not only comfortable to lie on but also has a couple of other features I really want to discuss. The FlexTech backrest has built-in handgrips, and this gives you something to grab onto if you’re going to stretch out your upper back side to side. You don’t see this feature with a lot of other inversion tables on the market.

Both models also come with acupressure nodes, which are great for pressure point relief. The acupressure nodes are easy to pop in and out of the backrest so you can put them wherever you need them, or remove them entirely if you don’t want to use them.

If you have tight knots under your shoulder blades or other points on your back, the acupressure nodes are great for those. The different color acupressure nodes vary in height and intensity.

Another included feature on both the FitSpine X1 and X3 is the lumbar bridge, which is for your lower back.  You can attach the lumbar bridge to the backrest, and it fits comfortably under your lower back to stretch more if you need it.

Overall, the backrest is well designed, easy to clean, and is very customizable.

Advantage: Tie

Inversion Angle Adjustment

Adjusting how far you will rotate backward is simple with the tether strap on these Teeter inversion tables. There are some differences in these models, so let’s talk about that.

I want to start with the FitSpine X3 because that will make it easier to illustrate the difference between the two tether straps. The X3 uses the EZ-Angle Tether which has preset marks sewn to the strap itself.  These marks indicate inversion angles of 20, 40, and 60 degrees.  The marks are color-coded according to the angle you want.

With the preset marks on the X3, you also have a good idea where to set the strap if you want to invert at an angle of say 30 degrees, which would be between the 20 and 40-degree marks.

The X1 does not come with the EZ-Angle strap, but rather a standard strap, so there are no preset inversion angle marks. The standard strap with no markings can make finding a precise angle more challenging.  My Teeter inversion table is set up this way.

The beauty of the tether strap, regardless of the FitSpine model, is that you are not limited to preset angles like you are with other inversion tables that use a pushpin type of mechanism.  With a pushpin type, you are limited to inversion angles of 15, 30, 45, etc.  With the Teeter inversion tables, you can set the angle anywhere you want with the strap.

Having unlimited inversion angles is a great feature, and I will tell you why.  When I was recovering from a pretty severe back injury in 2016, I had to start with a very shallow angle, like 15 degrees.  As I progressed in my recovery, I was able to increase the angle slowly.  There was no way I could have made a 15 or 20-degree jump when I was first recovering, so the pushpin system would not have worked for me.

Okay, enough on inversion angles, let’s declare a winner in this category.

Advantage: FitSpine X3 with the color-coded angle markers.

User Height Adjustment

Adjusting the user height on both of these tables is simple with the height markers on the main shaft.  You choose the height that corresponds to your height and start there.

You should be able to move in and out of rotation using your arm movements.  Depending on your body type, you may have to set the height on the main shaft higher or lower than your actual height.

Advantage: Tie, both use the same mechanism

Ankle Locking System

You want to feel secure when you are hanging upside down. The ankle locking mechanism on the FitSpine inversion tables consists of the locking/release handle, the footbed (what you step into) and the ankle cushions.

Both the X1 and X3 have adjustable height footbed, which is an excellent customizable feature.  The ankle cushions are contoured and fit snugly around your lower leg on both models.

The significant difference between these two FitSpine models is the locking/release handle.  The FitSpine X1 has a short handle, and the FitSpine X3 has a long handle.  The longer handle requires less bending over, and that is critical if you are dealing with a back injury and can’t bend over.  I will explain.

When I was recovering from a back injury several years ago, I had a lot of trouble bending over to put on my shoes and socks. I literally had to have my wife dress me in the morning.  Using an inversion table with a short handle was not an option for me since I could hardly bend over to get in and out of the inversion table.  I needed to use my inversion table as part of treating my sciatica.  Anyway, you can see the value of the longer handle.

Advantage: FitSpine X3

As for other features, both models have these in common:

  • Five-year warranty
  • FDA-Registered
  • UL-Listed
  • 3D interactive assembly instructions via BILT app
    Some assembly is required with both of these models, but Teeter has made this process very efficient.

Conclusion: Teeter FitSpine X1 vs X3

Both of these inversion tables offer great value, and you will need to figure out which features are most important to you. These models have some similarities, but also some stark differences.

I recommend the FitSpine X3, based on the fact that it comes with the EZ-Angle tether strap for easy inversion angle adjustments, and this table has the long locking/release handle.

If you can do without these features, then maybe the X1 is the choice for you.  No matter which table you chose, hopefully, your inversion table search ends here.
