7.9 Overall Score Reviewed By Experts

How do you like the idea of hanging upside down with the mere support of your ankles? Not very appeasing, right? Well, we did not like the idea either until we came across the Ironman Gravity 4000 inversion table! The Ironman Gravity 4000 has mastered the art of inversion therapy. With its traction detraction effect, it’ll be your perfect companion on the journey to a fitter body.

The backrest is lined with memory foam making it extra comfortable and supportive. Being slightly on the heavier side, it is extremely sturdy and the additional non-skid floor stabilizers make it well-balanced and safer for use, when inverted to 180 degrees. It not only relieves you from your constant back pain but also tremendously improves your blood circulation and relaxes your body. It is provided with extra-long handles and well padded ankle clamps ensuring extra comfort and support. Unlike the Ironman Gravity 1000, it comes with a ratchet system for locking the ankles, establishing more safety. The biggest lure, however, is its easy-on-the-pocket price!

Highly durable, easy to assemble, easy to operate, comfortable, effective and an absolute value for money, you will not regret purchasing it.

About the Ironman Gravity 4000

Size & Storage:

Although foldable, the Ironman Gravity 4000 does not completely fold flat making storage quite inconvenient. It cannot be pushed away into a closet or slipped under the bed. Leaning it against a wall is the best storage that it offers. To store it away, you will have to dismantle it entirely. However, during use it does not require too much space. The frame is adjustable to accommodate up to a 6’6” tall person.

Installation & First Time Setup:

Unlike a lot of other inversion tables, which claim easy assembling but are in fact not so, the Ironman Gravity 4000 is extremely easy to assemble and is not that time consuming. It took on an average 30-40 minutes for us to completely assemble the table. The instruction manual gives clear instructions and the tools for setting up the same are also provided. Considering that is quite heavy, you might require assistance in putting it together.
