Curved Treadmill Comparison Guide

AssaultRunner Pro vs. TrueForm Trainer and AssaultRunner Elite vs. TrueForm Runner

AssaultRunner vs. TrueForm: Curved Treadmill Showdown

If you're considering a curved treadmill, chances are you're looking for something that promotes better running mechanics, delivers a more demanding workout, and operates without electricity. Two standout brands in this category—Assault Fitness and TrueForm—offer leading options in both home and commercial settings. The AssaultRunner Pro and TrueForm Trainer are excellent entry-level models, while the AssaultRunner Elite and TrueForm Runner cater to more advanced or commercial users.

The AssaultRunner Pro is built for home gyms, offering a low-maintenance, motor-free design with Bluetooth/ANT+ compatibility and a variety of onboard training programs. It features a compact footprint, UV-resistant console, and 100 precision ball bearings, delivering a fluid, responsive run. Meanwhile, the TrueForm Trainer emphasizes form and feedback. Its shallow curve encourages natural stride mechanics, while the responsive belt technology and heavier construction offer excellent stability and control. It also supports up to 500 lbs and is equipped with modular upgrades, making it a future-proof investment.

For those seeking the highest level of performance and durability, the AssaultRunner Elite and TrueForm Runner are both exceptional choices. The AssaultRunner Elite elevates the Pro’s design with added storage, larger side shrouds for safe foot placement, and upgraded corrosion resistance—perfect for high-traffic gyms or athletes pushing longer sessions. It’s also backed by a 10-year frame warranty and a lifetime belt guarantee.

The TrueForm Runner, hand-built in the USA, is widely regarded as the gold standard for curved treadmills. With full customization options—including frame color, tread surface (rubber, turf, track, Naboso), and your choice of display—it’s designed to meet the exact needs of professional athletes and high-end training facilities. The optional TrueTouch display adds connected features like Netflix, Zwift, Bluetooth integration, and HDMI output, turning your treadmill into a multifunctional smart device. Most notably, the Runner’s unmatched responsiveness helps correct form in real-time, making it a valuable tool for both performance and rehabilitation.


In summary, if you're looking for an intuitive and effective training tool with built-in programs and simple setup, the AssaultRunner Pro delivers outstanding value. If you're focused on biomechanical accuracy and elite customization, the TrueForm Runner is unrivaled. Both brands provide rugged, non-motorized treadmills that burn more calories, improve form, and reduce injury risk—but your choice depends on how much you want to tailor your experience and how durable your treadmill needs to be for your space or facility.
