The XTERRA TRX4500 is one of the new treadmills released by XTERRA Fitness at the beginning of 2018. Even though it’s not labeled as a commercial-grade machine, it definitely has the sturdiness and range of features of a light-commercial model. It’s similar in dimensions to the TRX3500 model but does have a more powerful motor, a few extra incline levels, and superior deck cushioning.

Frame & deck
The XTERRA Fitness TRX4500 features a heavy-duty steel frame, similar to light-commercial treadmills. Its base and console masts are made of durable steel tubing, but the machine also has several ABS parts. Among them, we can count the covers of the rear part of the deck, the side covers of the masts and base joints, the motor cover, the dashboard of the console, and the covers of the side grips.
The fully assembled machine is considerably heavy. It weighs approx. 221 lbs (100 kg), and therefore, at least two people are recommended for the carrying of the box, the unboxing, and the assembly. Once assembled, the unit isn’t too difficult to move, though. Its front base has two small transport wheels. Also, the front and rear bottom sections of the frame have adjustable stabilizers.
The whole frame is coated with a corrosion-resistant and chip-resistant paint finish. The color used is light gray, while the ABS parts are black.
The machine’s deck is extremely sturdy. It can hold users up to 350 lbs (159 kg) with no problem, for any type of workouts. It also integrates XTRASoft cushioning elements (two on each side), in order to alleviate an important part of the shock created during running. This being said, running on this treadmill is considerably more forgiving on your joints than running on asphalt or concrete.
The fully assembled unit is fairly large. It’s approx. 77″ (196 cm) long, and 35″ (90 cm) wide. Plus, it’s recommended to allow at least three feet of clearance at the end of the deck, and at least two feet of clearance on each side of the unit.
This XTERRA treadmill is equipped with a 2-ply Duraweave heavy-duty belt. It’s designed to provide superior adherence for any type of athletic shoes. It offers a running surface of 60″L x 20″W (152.4L x 51W cm), which pretty much means that it promotes a complete and satisfying stride for users up to 6’5″ (196 cm).
The integrated rollers that set the belt into motions are crowned, in order to prolong the life of the belt. The front one is 2.4″ in diameter, while the rear one is 1.8″. They’re equipped with high-grade ball bearings and supply a very smooth belt motion.
Last but not least, the unit’s frame is foldable. The deck can be folded and locked up at approx. 65°. Therefore, the unit’s length is reduced by approx. 40%. The folding mechanism features a Lift Assist function and a Safe Drop function, to make sure you securely fold or unfold the unit.
Incline & step-up height
The XTERRA TRX4500 treadmill is equipped with a motorized incline system. It consists of a small lift and a motor, placed at the front of the deck. The control of the incline is done from the console or the buttons incorporated into the side grips. Also, in case you select a workout program that involves incline, the machine will auto-adjust the incline accordingly while you walk or run.
The unit’s incline ranges from 0% to 15%. The adjustment increments are 0.1%. At 0% incline, the surface of the deck is approx. 9″ (22 cm) above floor level, while with the incline set at maximum, the front of the deck will rise by several more inches. Thus, in order to avoid any issues, it’s recommended to use the machine in a room with a ceiling that it’s at least 20″ (51 cm) higher than your own height.
The XTERRA Fitness TRX4500 features a heavy-duty 3.25 HP motor designed to support long runs at maximum speed, without overheating or losing performance. A small flywheel is attached to the side of it in order to reduce vibration. This leads to a smoother motion of the front roller.
The motor offers a speed range between 0.5 MPH and 12 MPH. Just as for the incline, the console features controls for gradual speed adjustment and quick speed adjustment. However, the quick keys for speed adjustment only cover the settings from 1 to 10 MPH. So, if you want to increase the speed further, up to 12 MPH, you will have to use the arrow controls on the console, or the ones integrated into the right handlebar.
The gradual adjustment keys offer the possibility to adjust the resistance in increments of 0.1 MPH and 0.5 MPH. By pressing one button repeatedly, the speed of the belt will be adjusted in increments of 0.1 MPH, while when pressing and holding the button, the speed adjustment will increase to 0.5 MPH. This is quite a useful feature as you can easily find the most comfortable pace for your workout. Also, since the top speed setting is 12 MPH, the machine offers the possibility to perform sprint workouts and interval workouts.
The XTERRA Fitness TRX4500 features a programmable console. To begin with, it has a 7.5″ LCD display with LED backlight and large digits for superior readability. Its top section indicates pace, calories, time, distance and pulse. The mid-section shows the speed, the incline level and the program segments, while the bottom section shows the selected user.
The console has 30 preset programs, 2 custom user programs, 1 HRC program, and the manual program. The 30 preset programs cover workouts of all kinds, for an intense burn, stamina, or intervals of high cardio. The 2 user programs give you the possibility to create your own custom programs. The HRC program allows you to select a determined HR interval and the machine will adjust the speed in order to keep you within the specified HR interval for the duration of the program. The manual program allows you to freely adjust the incline and speed as you walk or run.
Speed and distance can be set to metric or English units. For distance, there is a race track function which displays the distance traveled as a 1/4 race track, counting the completed laps. The console is also telemetric; it can track your pulse via the included HR chest strap, but you can also use the pulse sensors within the handgrips.
The console is also Bluetooth enabled, and compatible with the XTERRA Fitness App available from the Apple Store or Google Play. If you download this app into your phone or tablet, the machine can directly stream your workout data to the app allowing you to sync it to the iHealth or FitBit for a better tracking of your progress.
Apart from the fitness functions, the machine’s console also integrates several amenities. These are a sound system, a cooling fan, a tablet holder, and two accessory holders.
Assembly & Maintenance
The treadmill’s deck with its motors comes pre-assembled and attached to the metallic base frame. The only parts that require assembly are the side console masts, and the console. The procedure may take more than 30 minutes, but it’s far from being complicated. On top of that, the user’s booklet provides very clear assembly instructions and a basic toolkit is also included.
In terms of maintenance, the belt requires periodic lubrication (after every 180 hours of use). However, it’s pre-lubricated so it shouldn’t need further lubrication for your first 180 hours of use. The running belt should be wiped clean with a damp cloth after every workout to prevent any small objects or textile fibers from being dragged into the motor or the rollers.
