Differences TrueForm Trainer vs AssaultRunner in-depth
Individuals who know a lot about manual treadmills features and know what they want may be able to make a decision with the help of the differences overview and a quick look at the prices.
On the other hand, you could also be unsure about what certain features mean and to what extent they should influence your decision.
In a situation like that, it can be helpful to look at the more in-depth explanations below.
Overall sturdiness and weight limit
Before looking at all other feature differences between the TrueForm Trainer and AssaultRunner you have to make sure each treadmill can deal with the pressure you intend to put it under.
Both the TrueForm Trainer and AssaultRunner are steel constructions with a plastic cover. Even so, due to other material choices and construction, the Trueform Trainer is just a bit sturdier.
The mentioned user weight limit for the TrueForm Trainer is 400 pounds (181 kg). For the AssaultRunner Pro, this is 350 pounds (158 kg).
Even if the individuals who will use the treadmills are nowhere near these numbers, they do give some indication of how the TrueForm Trainer and AssaultRunner Pro compare in sturdiness.
Most individuals will find the AssaultRunner Pro more than good enough too but if want to play it safe in this area, it may be smarter to choose the TrueForm Trainer or potentially the more deluxe TrueForm Runner.
Winner: TrueForm Trainer
General tread feeling from users
Even if you know that the AssaultRunner Pro is more curved than the TrueForm Trainer and what materials and constructions are used in each treadmill, you likely do not have too much of an idea about how it feels to run on them.
In this situation, user comments can be helpful. First of all, these users tend to find the AssaultRunner Pro belt heavier and longer than the belt of the TrueForm Trainer.
Some people mention that these things make it so the AssaultRunner Pro feels better for sprints where you use bigger strides. On the other hand, some users find the TrueForm treadmills more convenient for longer distances.
Additionally, there are mentions that the TrueForm treadmills feel more like running on the road than the AssaultRunner Pro.
Something to note is that the heavier belt of the AssaultRunner Pro tends to stay in motion more due to the extra momentum. You have to be careful when slowing down and potentially have to step off the belt.
Another thing users mention a lot is that they feel the TrueForm treadmills guide them towards forefoot running. This can be helpful to internalize this running technique but can be challenging initially.
On the other hand, the AssaultRunner Pro is generally more forgiving for other running techniques like heel strike and midfoot landing.
These things are not necessarily better or worse for every single individual. You may prefer the feel of either the TrueForm Runner or AssaultRunner Pro because of your running technique, training program, and personal preferences.
Winner: Depends on personal situation and preferences
Monitor
Treadmills generally come with some type of monitor or screen to show things like speed, distance traveled, time, etc.
Both the TrueForm Trainer and the AssaultRunner Pro have these more basic features and a way to connect a heart rate measuring device to the screen through Bluetooth.
That being said, the monitor of the AssaultRunner Pro is definitely more pleasant on the eye and more convenient to use than the one from the Trueform Trainer.
Additionally, the AssaultRunner Pro comes with a few workout types built-in. These include quick start, intervals, targets (of for example distance), and competition mode.
In short, most people will prefer the monitor of the AssaultRunner Pro.
How much you value these differences between the monitors depends on things like personal preferences and how you approach your treadmill training.
Winner: AssaultRunner Pro
Price
The exact feature differences between the TrueForm Trainer and the AssaultRunner Pro are not the only things that matter. For most people, the prices will matter to at least some extent too.
Exactly how much of a difference there is depends on things like where you buy your manual treadmills and can change over time.
However, at the time of writing, the AssaultRunner Pro is a good amount more budget-friendly than the TrueForm Trainer.
Unless you really care about the feel, parts warranty, and extra sturdiness of the TrueForm Trainer, the AssaultRunner Pro is likely more worth it.
If you don’t care too much about price, want an even sturdier manual treadmill with different running surface options, and want long warranties, you can even consider the TrueForm Runner.
Winner: AssaultRunner Pro
