Overview of the trueform runner
The TrueForm runner is the latest and greatest in the treadmill industry. Compared to other treadmills it has the advantage that it is not motorized and propelled by your own weight. In addition, the surface you run on is curved so the impact of your footfall is not as hard as on a flat surface. This dynamic is achieved by a conveyor belt that runs on bearings. Think of the conveyor belt at the airport but moved by your own bodyweight. It has been used at the CrossFit games and has gained popularity since then. The dimensions of the TrueForm runner are:
- Height 57’’
- Width 36’’
- Running surface 54’’ x 17’’
- Weight 325 LB
You can choose from two different options, Enduro and Performance. Both options come in at the same price and with the same dimensions. The performance model provides a higher railing. This is especially useful when you have athletes who run very fast on the machine.
Apart from this, you can pay $500 extra to get grass or track and field topping on the running surface. If you use the TrueForm runner to train track and field or football athletes you might want to go with one of these options.
Pros of the TrueForm runner
There are several pros to the TrueForm runner
-
Better posture
-
Easier adjustment of speed
-
No power supply needed
-
No programming needed
-
Less impact
-
Good resell value
-
Low maintenance
Based on the setup of the Trueform runner it actively helps your clients and athletes to have better running form. If you strike with the heel the curve of the machine will help to remedy and correct this over time as you push the belt from the front to the back.
With the Trueform runner, you can adjust the speed at any given time yourself without worrying about faceplanting. Doing interval training on motorized treadmills can be really annoying as the acceleration and decelerations come in jumps rather than continuously when you program them in at the start of your workout. If you adjust them while exercising it is almost impossible, especially at high speeds.
If you deploy a whole row of these (10 - 20 machines) you might also be pleased that you do not need to plan for cabling when the gym is built and powering these treadmills all year around.
As mentioned before you can free run on these machines to your hearts contempt. No buttons or panic stops needed. Just slow down and the belt slows down with you. You will not be catapulted into the wall behind you.
The curve will also be helpful to have less strain in the ankles and knees from the impact of the food. This helps you to train longer for harder.
As with most things which are "hip" and high price you usually get a higher resell value out of them than for the lower range options. While this is mostly less important for individual buyers it can be important for a chain that regularly closes off unprofitable subsidiaries and wants to shuffle equipment around.
As there are no motors which can break down you will also have fewer maintenance needs. Although you are probably more likely to need a welder rather than an electrician when this beast breaks.
Cons of the TrueForm runner
The cons of the TrueForm runner are in my opinion:
-
Hard to do pace training
-
Not for beginners
-
Price tag
-
A big piece of equipment
-
Poor monitor
When I prepared for my marathons there was one thing I liked about treadmills, you could set an exact pace for some of your long runs. This is actually a strength rather than a weakness of a motorized treadmill. For me, it was handy to plan my splits and hit my target time as the pace I chose was slightly challenging. I would do one of these a week slightly above the planned pace for the marathon and add distance each time. The rest of my training would be outdoors. This raised my confidence to reproduce the exact pace I needed on race day. With the TrueForm Runner, it would have been hard to have that reference, but it would have been better to do Interval runs indoors.
Tell me what you want but this thing is not for beginners. This is designed for people who want to go like cheetahs and could not do it properly on normal treadmills. Fast acceleration and breaking are where this is at home. Not for beginners or someone who is wobbly on their feet because they do rehab or are overweight. A slow motorized treadmill is the better option here.
With $5000 a piece, this is a steep price. If you want to signal to your clients that you are doing well and justify the membership of $300 a month, this is a strategy. For two of these, you can get a 10 pack of concept 2 rowers, skiergs or bikes. 10 x $100 in membership fees from a spinning class is more than 2x $300 with a bigger spread of risk in your income.
Last but not least these are big. If you have a garden or basement gym I would almost consider this no option unless you live in a mansion. If you want to maximize floor space in your commercial gym this is also not the way to go. CrossFit boxes might like this, especially if they are in the middle of a busy city.
The monitor is poor compared to some of the concept 2 options where you have leaderboards implemented to keep yourself motivated.
Alternatives to the TrueForm runner
The assault air runner is one alternative to the TrueFrom runner if you still want a self-propelled treadmill. The assault air runner comes in at a lower price point than the TrueForm runner. The mechanics are also a little different which makes running easier on this one.
The Versa Climber is often referred to as one of the hardest things you can do in endurance on a machine. It simulates climbing a steep wall with a good grip. It comes in at about half the price and takes up less footprint than the TrueForm runner. If you want a good machine for your home to knock you out this is can be a great pick. For a commercial gym, you might not have the uptake as many people just want their treadmills.
The Rogue Echo bike is a solid choice for the home gym that wants to kick your butt. Combined to the Versa Climber and the TrueFrom Runner it comes in at a fraction of the cost. A good air bike workout will still challenge you and is highly recommended.
Summary for the TrueForm runner
This is a well-built piece of equipment which is worth the price if you have the need and space for it. Athletes who know how to pace themselves, have balance and want every workout to be as challenging and adaptable as possible will love this.
For the average gym with average clients it is probably a bit too intimidating and high performance. I do not see overweight stay at home moms or retired manly beer bellies stepping on the TrueForm runner first thing through your gym doors.

The main features of the Nordictrack S40 are its 3.0 CHP motor, the 12% incline, and the one-touch controls. Unfortunately, the S series is one of the older product ranges of the Nordictrack line up and you might want to look into the C1650 or T7.5 as an alternative. Still, you might make a good grab on the used treadmill market for this model. The full list of features includes:

Have a good look at the market what you can get, but this treadmill might not be an ideal choice for buying something new.
Pros of the Nordictrack S40
- 3.0 CHP motor
- One-touch controls
The 3.0 CHP motor makes this a long-lasting treadmill for someone who runs a lot. Especially used this might be a good steal. The one-touch adjustments for speed are also a great feature of Nordictrack treadmills which make them more user friendly as you only need to push one button to get to the right space.
Cons of the Nordictrack S40
Cons of the S40 are:
- Price
- Age
For the age of this product line, you still pay a pretty high price. This is good for Nordictrack to empty their inventory of old models, but not necessarily for your purse. If you buy new you may want to get for the newer models in the X line or the T line which have followed the C line of Nordictrack models.
Alternatives for the Nordictrack S40
Good alternatives for the S40 are:
The Nordictrack T7,5 is, in my opinion, a better alternative to the S40 unless you manage to get a discount on the S40. The T7.5 is the more modern machine and has almost the same specifications. They also punch in the same budget weight class. So stick with the T7.5 instead of the S40 in the Nordictrack portfolio.
The FS5i is a good alternative for an elliptical for a home gym or commercial gym. It costs roughly the same as the S40 and comes with Free Stride technology. The FreeStride technology puts the flywheel in the middle of the machine. This enables a longer stride and you can also use the elliptical as a treadmill, elliptical, and stepper in one. This freedom comes at the price of a more error-prone design and more challenging movement patterns.
If you want to save some money and like rowing, you can go for the Concept 2 Model D rower. This is the flagship model from Concept 2 who has been around for years in the rowing place. You will be hard-pressed to find a major commercial gym without one of these on the floor. They come in under 1000 and might be a get alternative to consider. The only challenge is that they take up as much space as a treadmill, but are easier to move.
The Rogue Echo Bike is my personal favorite for home gyms as it is compact, sturdy, and burns a lot of calories per minute if used right. This machine can be gotten at the 700 mark and will last for a lifetime. The big disadvantage is that the Echo bike has no onboard entertainment whatsoever. If you need a video or machine to motivate you to get your training in, this is not the one for you. This is a great tool for intrinsically motivated people who want to save money and space.
Summary for the Nordictrack S40
As with the entire S series you might want to opt for something else which is a little more modern and therefore will get more support from the vendor Nordictrack. Always check the US website and compare the portfolio with the Uk website to avoid that you are buying something with is being discontinued. At the time of writing the S series is not available in the US anymore where Nordictrack headquarters is situated.
