The ironman ATIS 4000 inversion table could be the perfect choice if you’re looking for a positive locking inversion table capable of full lockout routines. Read on to find out what I learned while researching this inversion fitness power house.
I was surprised to learn that it was possible to lock this unit into 10 different levels of incline without the use of those annoying safety tether straps. There are a couple of possible draw backs to this unit so be sure and read all the way through before making up your mind on whether this AB Inversion Training System model would be right for you.
The Ironman ATIS 4000 is designed to be used as a fixed set-up (does not fold) heavy duty decompression unit. The ATIS 4000 is constructed of heavy walled round tube steel which is powder coated for years of dependable scratch free use.
[toc]The backrest assembly frame is a combination of square tube steel and round tube steel for extra heavy duty support. This is why the Ironman ATIS 4000 is rated for use up to 320 lbs. unlike the 250-300 lb. rating of must other brands including the Teeter Hang Ups EP 560 Series.
Unlike many other models, even units from Ironman, the ATIS 4000 uses a round steel tube one-piece pivot bar assembly that comes connected directly to the main upright frame assembly. So you should find assembly easier than many other tables because there are three major sections assembled at the factory.
This table includes heavy duty rubber foot pads on all four corners to assure solid mar resistant support for the user and unit.
The backrest assembly of the Ironman ATIS 4000 incline table features a 2-1/2” thick foam padded main backrest as well as an extended head rest pillow. The main backrest section is 18” wide at the lower end and is 35” long plus you gain and extra 8” of length with the extended pillow section.
If you’re concerned about width inside the backrest area, you will find 18” of space between the two blue pivot assemblies. In all my research I didn’t find any negative responses about this width not being adequate for user comfort.
The Ironman ATIS 4000 Incline Table uses my favorite ankle support system. Basically the same system used on my Ironman Gravity 4000 unit. This ankle support system combines both front and rear cuff style comfort support pads. This pad combination offers the most comfortable user experience of any ankle support system.
When you combine these ankle supports with a one-hand operation, extended handle, palm activated, ratcheting safety ankle lock system, you have put together the best possible user experience. The safety ratcheting lock means a simple push of the palm button then pivot the front assembly against your ankles and release button for a safe secure lock-in. Simply reverse this process to exit the ankle lock assembly.
Now it’s time to talk about ATIS (AB Inversion Training System) which is the most exciting feature of the table. With the ATIS breaking system you will be able to lock your unit into any one of ten different incline controlled angles without the use of a safety tether system like you find on other units.
This means that no matter whether you plan to use your bed only for decompression or if you plan to advance into a fitness training program with your bed, you will be able to safely lock the unit into a set position where it will not move forward or back until you release the breaking control.
The ATIS 4000 control system works with a simple handle that engages a strong metal bar into one of the ten possible incline angle cogs to lock the platform at that angle. It’s worth noting here that once locked in place, there will still be a slight movement until the bar seats firmly in the cog slot. Likewise, unlatching the bar lock might require a slight movement in the other direction to take pressure off the bar-cog assembly.
The Ironman ATIS 4000 is designed to be able to invert to full 90-degree lock-out with the option of setting the brake assembly or hanging by free suspension like tether style units. Because of the break locking feature you will be able to perform AB workouts including crunches, sit-ups, inverted squats, hip rotator exercises, and stretching routines at virtually any incline angle. (see video below)
The Ironman ATIS 4000 decompression system is designed for users from 4’-9” to 6’-6” in height, weighing up to 320 lbs. As with any incline unit, it’s important to understand that your best height setting will be determined by practicing with your new table between 1 and 2 positions higher or lower than your actual height until you find the setting where you achieve perfect zero balance with your new table.
For your workout you will find 2 fixed stretch assist handles mounted to the lower frame as well as the 2 extended reach foam padded assist and stretch handles mount up around the pivot assembly.
Assembly & Storage
The Ironman ATIS 4000 Incline Table comes with three major sections assembled from the factory. These sections include the lower leg assembly, Main upright frame assembly with pivot control device, and the main backrest frame assembly. Because these parts come factory assembled expect a much larger shipping container that many models which come in smaller pieces.
The owner’s manual that comes with your new ATIS 4000 is pretty straight forward and written in both English and French with good visual pictures. It does include an exploded view of every part as well as a complete parts list should you ever need replacement parts. This exploded view can seem intimidating when you first open the manual, but you will find easy to follow assembly instructions beginning on page 11.
When it comes to unit space and mobility requirements, it’s important to note once again that this is a fixed position table. This means that good planning as far as a destination and usage location is key before assembly begins. Once assembled the unit weighs 111 lbs. and will require a full 36” wide doorway to pass through. The unit does not fold, so if you’re considering the ATIS 4000 then plan on a permanent space 35” wide by 58” long, but keep in mind that you will need about 7’ of total length centered at the pivot point when inverting the table. I’ve found they work great in the corner of a room since the head area can invert into the corner limiting how far the unit sits out in the room.
This unit would be ideal if you are planning a home gym or fitness room because of its solid stable design and the fact that with the AB Inversion Training System built in it will serve as a valuable workout partner. Which brings up another valuable point, you should not need a spotter with this unit so long as you are in good physical health (no blood pressure problems, headaches, or dizziness). I have never used a spotter with my inversion table and neither does my wife.
Here is a link to compare all my inversion table reviews on one page. With individual unit details and links to each of my reviews.
When it comes to safety, I think the ironman ATIS 4000 is in a class that sets it apart from standard tether type incline controls. With its user controlled positive locking system you will have complete control of your incline level. This can be a concern also though, as the system has no other form of inversion limit control. So while this should provide a good user experience, beware when first using this unit until you are familiar with its inversion controls.
I always make mention here that before using any incline equipment you should consult my article on decompression health concerns in order to determine if decompression therapy is right for you.
The Ironman ATIS 4000 inversion table includes an attached side mounted holder to conveniently set your phone, keys, or any loose change before inverting.
As I mentioned above, the ironman ATIS 4000 inversion table is designed to be assembled and left in one place. Because of its weight 111 lbs. assembled and due to the fact that it does not fold down for storage, this unit is not designed to be moved from room to room. Its footprint once assembled is 35” wide by 58” long but you should allow a full 7’ of length for full horizontal incline. The unit will fit through a full 36” wide door if you decide to move it but none smaller. The unit shipping weight is listed at 113 lbs.
This unit is designed to be a permanent set-up in your home. It is not designed to fold or be moved around. I would recommend this model for anyone considering a home gym or dedicated fitness room or who can spare about 6’ by7’ of space in the corner of any other room. The corner seems to work best because it allows the unit to incline into the dead space of the corner without taking up too much space in the room.
The ATIS 4000 has a 1-year frame warranty with a 90 coverage on other parts direct from Paradigm Health and Wellness, Ironman’s parent company.
