The TRUEFORM.TRAINER™ is a curved manual treadmill. It is a rugged, quality-built cardio solution for any home gym or sports facility. Designed to be virtually maintenance-free the non-motorized TRUEFORM.TRAINER™ is great for the environment - no electricity needed.

The TRUEFORM.TRAINER is a Get On and Go Workout. Simple and user-friendly for all ages and skill levels - and ideal for team events and relays. It offers a budget-conscious alternative to the USA hand-crafted RUNNER and its lighter weight and compact size make it easy to move and maneuver for indoor and outdoor HIIT and other competitive sporting events. Want to take your TRAINER up a mountain? No problem, we’ve done that!

Make no mistake, the TRUEFORM.TRAINER is still a workhorse of a treadmill, with its steel frame construction and heavy-duty, impact absorbing slatted running surface handling users up to 400 pounds running at top speed.

With its gentle curve of 2.5 inches from the lowest part of the curve to the highest point near the front and rear, the TRAINER provides the least steep curve on the market, which promotes good walking, running, and sprinting form. The shallow curve also allows you to easily and safely control your speed.

The proprietary Responsive Belt Technology™ reacts to every subtlety in your movement – balance, posture, hip position, foot strike and more – creating the most natural treadmill running surface and experience when compared to running outdoors. You will immediately feel when your body is not in the optimal position for running or walking. The runner has to be in balance at all times, improving core strength. Although you will feel the difference immediately, both on and off the Trainer, long term use of TRUEFORM™ treadmills will promote better movement patterns improving overall health and wellness.

Training on the TRUEFORM.TRAINER treadmill results in less stress, more effort, 33% higher calorie-burn, more balanced movement, and running under properly positioned load to support your own bodyweight, all while reducing the risk of running injury. Run strong and stay injury free!

    Making a TRUEFORM purchase is an important step towards meeting your goals and we want to help you find the right configuration.

    Trueform Surprise

    I was nervous about my Trueform purchase. I had never used a manual treadmill before but I heard a lot of positive reviews of the technology. I can say that it is all true. I would never use a motorIzed treadmill again if given the option.

    and my clients love them too! They are super durable! They've been great for training athletes, the general population, and I'm using them to train myself to run over 100 miles at one time.

    Helps improve your actual runs times.

    You’re the “motor” and will expend more energy to keep the 65LB belt moving. Noticeable improvement when I’m on actual pavement. Great piece of gear.
