Ironman Gravity 4000 Inversion Table Review


  • Comfortable Ankle Locking.
  • Long Safety Handles.
  • 5-inch memory foam on the backrest.
  • Wipe clean vinyl design.
  • Reinforced stitching.
  • Thick tubular frame.
  • Durable Powder Coating.


  • The Ironman Gravity 4000 is a little weighty and difficult to store. However, it is much stronger and more durable than other inversion tables so the trade-off is worth it.

Design and Durability

The Ironman Gravity 4000 can support extremely heavyweights, so even if you are a contender for the title of World’s Strongest Man, you can use this table and be confident that your weight will be held up to 350 lbs!

The wider tubular frame design ensures that the table can withstand heavyweights. Powder coating completes the design and adds to the rigidity of the table. An added bonus of powder coating over a standard smooth paint finish, is that scratches and cosmetic damage don’t show up as much on powder coat finishes.


To add to the stability and rigidity of the design, the Ironman Gravity 4000 features a tough stabilizer. This is made from durable rubber to ensure that the U-shaped frame can stand as strongly as possible without the risk of slipping or causing damage to the floor during use. All this does make the table a little heavy, so you should be sure to have at least one other person to assist if you need to move the unit.

The frame features safety handles that can be used to pull back up on to get out of the inversion. It also means the inversion can be controlled with the hands.

Backrest and Positioning

The Ironman Gravity 4000 has 3 different positions for inversions to give as much flexibility as possible to the session. Depending on your level of expertise when it comes to using inversion tables, you should position the table accordingly.

By using the various positions, you can control how far you can safely invert. This ensures maximum peace of mind whilst using the equipment. There is also an adjustable strap that is used as a tether. This provides added safety and will not allow the inversion to exceed that limit.


The backrest on the Ironman Gravity 4000 is solid in design and is covered with a strong and durable vinyl material. The wipe-clean finish makes it simple to look after this inversion table.

To add comfort whilst using the Ironman Gravity 4000, the backrest features a 2.5-inch thick layer of memory foam padding. This is high quality and will last the test of time.

There is additional stitching in this model compared to older models. This reinforces the backrest to ensure the table can withstand expected wear and tear. Finally, the backrest is wide enough to comfortably lie on without feeling like you may fall off the edge.

To support the lumbar area and allow for the natural curve of the spine, the backrest incorporates a lumbar pillow. The pillow gives some leeway for adjustment. Although users who are particularly short in stature may have some difficulties getting completely comfortable.

Ankle Locking System


When using an inversion table, the user is held using ankle supports in an inverted position to enable the back and other muscles to be stretched to achieve maximum benefit. Whilst the amount of time that the user is inverted for isn’t very long, the most important aspect of this process are the ankle locks to ensure that the ankles are comfortable and safely held.

The ankle locks attempt to eliminate as much of the insecurity that you may feel when being inverted as well as any pain that may be experienced. In the heel portion of the ankle support is a carefully molded cushion, which is specially designed to lessen the discomfort that you may experience in your feet. The lock itself that secures around the ankles can be adjusted to create a tight hold.

Setting up the Ironman Gravity 4000

The Ironman Gravity 4000 does require some manual assembly. You should allow for between 60 and 90 minutes to give you time to put the table together. The instructions, however, are easy to follow and are clear so even if you’ve never assembled an inverted table before, you shouldn’t have much difficulty with setting up the Ironman Gravity 4000.

When you’re assembling the unit, you should probably get someone to help out, as it can get heavy. The table comes with all the fixings you’ll need. It also includes a mini screwdriver and wrench so you won’t need any extra tools or screws.

Storing the Ironman Gravity 4000

Although it is possible to fold the Ironman Gravity 4000 so that it can fit up against a wall or into a cupboard, you should bear in mind that this is a heavy unit so it may be difficult to frequently move around. It is also quite bulky so when it is stored, it can take up quite a lot of room. What the Ironman Gravity 4000 sacrifices in portability, however, it more than makes up for in strength and durability.
