The aeroSling Test

The aeroSling is the German counterpart of the TRX Suspension Trainer.  So it’s German engineering might in a fight with the American original for dominance in the Suspension Training market.   Elmar Schuhmacher and his company aerobis invented the aeroSling.

So, is there a home advantage for the aeroSling?  You’ll find out, reading my test.

 The test of the aeroSling I’ve also divided into four main topics:

  • Material
  • Setup, Safety and Comfort
  • Training
  • Overall Impression

Lets get started.


The aeroSling is relying on climbing materials, no matter which elements we’re talking about.  The anchor sling and the hand slings are made of a double nylon composite.  The slings consist of ropes which are made of a nylon composite as well.  The reason that aeroSling slings are made of rope is related to the unique revolving loop (more about that later).

All of the carabiners used (a total of three) are made by the company singing Rock.  This creates confidence.  The Bavarian enterprise, which has been supplying climbing products for many years, is known for most reliable materials.  Theoretically, the carabiners can withstand a load of more than 2 metric tons (approx. 4400 lbs), the same is true for the ropes used in the design.  But that’s just theory, the innovative aeroSling revolving loop has a disadvantage too: it doesn’t allow for such incredibly high loads.  The suspended pulley can withstand a load of 120 kilograms (approx. 264 lbs) only.

Handles of the aeroSlingThe use of high quality materials is a feature found in the grip handles as well.  Here the aeroSling is relying on an aluminum core combined with a hard rubber coating, a design, that is used for fitness center training devices too.  Even after 6 months of intensive training use there was zero wear and tear.

So the aeroSling makers clearly identified the TRX Suspension Trainers weak spot.  In contrast to the US product they clearly focused on quality.  An additional advantage is, that the grip handles are attached to the slings by carabiners, that way grip handles can easily be replaced or substituted with other types of handles.  For this purpose, aeroSling offers an abundance of accessories, among others, there are classic grip handles and flex handles.

Unfortunately, the aeroSling trainer doesn’t provide pre-installed foot loops.  According to the manufacturer’s website: “If you look at it realistically, you are mainly training with your hands.  In doing so, separate foot loops would always be in your way”.  Personally, I never experienced it that way while training with the TRX.  The problem, however, can easily be solved by slipping the aeroSling grip handles aside, working out in foot mode isn’t that comfortable, nevertheless it works.

Setup, Safety and Comfort

I always like to ask: What is it that really makes a difference when it comes to a Suspension Trainer (or Sling Trainer)?  The most important issues, from my point of view, are a fast and straightforward setup, an easy attachment to all kinds of objects, and a quick and uncomplicated way of adjusting the slings.  In a nutshell: the Suspension Trainer (or Sling Trainer) should be easily adaptable to your training needs.

Lets just keep that in mind :) .  There are several anchor slings affixed to the aeroSling’s attachment sling.  However, the aeroSling doesn’t employ carabiners for the attachment, it is using a system of grip knots instead.  From my personal point of view, this is a bit complicated and it’s not as easy to handle as the competitor’s solution.  So your first setups will take significantly longer, but in the end the aeroSling too will be safely and flexibly attached to all kinds of objects.  The new version of the aeroSling Sling Trainer is equipped with a door anchor as standard feature, so you can get started right away training at home (and there is no need for the towel trick).

Hint: For those of you who prefer carabiners…

If you prefer carabiners, you can always get an additional one for your aeroSling. It’s important to make sure that the maximum load capacity is adequate, after all, it’s the carabiner that holds your Sling Trainer in place. If you want to have a good carabiner, just order an additional one of those, already mounted to the aeroSling, from singing Rock.

Adjustment of teh aeroSlingFor sling adjustment the aeroSling is relying on a grip knot system, similar to the one used for the trainer’s attachment.  The slings feature an adjustable grip knot construct, it is operated by loosening the knot at two distinctive spots and then by pulling the sling through applying moderate force.  Next, you re-tighten the knot and the sling adjustment is complete.

Contrary to a clamping system, this, of course, is somewhat complicated and it takes more time to operate.  On the other hand, clamping systems tend to wear out, thus jeopardizing your training, a disadvantage not present when using a grip knot system.  Remind yourself however, what a Suspension Trainer (and again, or a Sling Trainer) is really all about: fast setup and quick sling adjustment.

Regarding both points the aeroSling is applying a material saving method, however, setup and sling adjustment simply take more time. 

Probably, the most innovative part of the aeroSling is it’s suspended pulley.  Here the slings come together, allowing for circular motion as well as “lifting and lowering” movements.

This innovation, however, comes with a certain safety risk.  In order for the new training methods to function well, you must ensure that the suspended pulley is running flawlessly, smoothly, and quickly.  Doing so, though, creates an unwanted side-effect: if you were to loose control on one side, the other side of the sling might completely slip through.  Worst case scenario: you end up face down sliding along the ground (this hurts of course, even more so, if the ground surface is rough).  Here is a simple trick for you to reduce this safety risk.

Hint: Sling layering

If you want to prevent the suspended pulley’s side-effect and at the same enhance safety, just layer the slings of the aeroSling several times. It works just like weaving (guys, have your girls show you, how it’s done ).

The aeroSling sling trainer On to the last subject: comfort.  The grip handles lie comfortably in the hand, thus allowing for a pleasant workout.  They are as firm as classic fitness center handles.  Personally, I like that very much, much better, in fact, than training with soft materials.  As I already mentioned in the first segment of the aeroSling test, the Sling Trainer isn’t equipped with separate foot loops and in foot mode you simply slide the grip handles aside.  To me, working out in foot mode was uncomfortable, at times the grip handle loops were rubbing unpleasantly against my ankles.  For those of you, who consider themselves to be tough guys, you certainly will stick it out, for everyone else, I can only quote the aeroSling website again: “If you look at it realistically, you are mainly training with your hands”.


Overall, all Suspension Training exercises can be conducted without problems, using the aeroSling.  By applying the sling layering technique, I described for you, you’ll manage to reduce the innovative suspended pulley’s unwanted side-effect.  However, the aeroSling has, with the suspended pulley, a genuine ace up it’s sleeve.  It greatly extends the exercise repertoire and makes your Sling Trainer workout more diversified.

Another advantage is, that the aeroSling can flexibly be enhanced by installing alternative grip handles.  That way you can add special focus and more variety to your training routine.

Overall Impression

Not least because of its flexibility, the aeroSling is making up for the ground it loses due to the more complicated setup.  Thanks to it’s suspended pulley, exercise variety is being greatly enhanced.  Thereby the aeroSling is priced at just 169€, that’s about 50€ less than it’s direct competitor’s price.  At the same time, it doesn’t compromise when it comes to top-quality workmanship and high durability.

For those of you, who are looking for a high quality alternative, and who like the fact that it adds a breath of fresh air to your Suspension Training, the aeroSling is just the right product.
