TRX4500 Frame

The XTERRA Fitness TRX4500 features a heavy-duty steel frame, similar to light-commercial treadmills. Its base and console masts are 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 console’s dashboard, and the covers of the side grips.

XTERRA TRX4500 Folding Treadmill

The fully assembled machine is considerably heavy. It weighs approx. 221 lbs (100 kg), and therefore, it is advisable for at least two people to carry 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 comes coated with a corrosion-resistant and chip-resistant paint finish. The color used is light gray, while the ABS parts are black.

The fully assembled unit is relatively large. It’s approx 77″ (196 cm) long and 35″ (90 cm) wide. Plus, it’s advisable to allow at least three feet of clearance at the end of the deck and at least two clearance feet on each unit’s side.


The machine’s deck is exceptionally sturdy. It can hold users up to 350 lbs (159 kg) with no problem for any workouts.

It also integrates XTRASoft cushioning elements (two on each side) to alleviate an essential part of the running shock. Therefore, running on this treadmill is considerably more forgiving on your joints than running on asphalt or concrete.

This XTERRA treadmill comes equipped with a 2-ply Duraweave heavy-duty belt. It provides superior adherence to any 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 full and satisfying stride for users up to 6’5 ″ (196 cm).

The integrated crowned rollers that set the belt into motion prolongs 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 reduces 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.

TRX4500 Incline & step-up height

The XTERRA TRX4500 treadmill comes equipped with a motorized incline system. It consists of a small lift and a motor placed at the front of the deck. The adjustment of the incline is from either the console or the buttons incorporated into the side grips.

If 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 slope set at maximum, the front of the deck will rise by several more inches.

Thus, to avoid any issues, it’s advisable to use the machine in a room with a ceiling that is at least 20″ (51 cm) higher than your 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 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. If you want to increase the speed further, up to 12 MPH, you will have to use the arrow controls on the console or 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 belt’s speed will change in increments of 0.1 MPH, while when pressing and holding the controller, 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 can perform sprint workouts and interval workouts.

TRX4500 Console

The XTERRA Fitness TRX4500 features a programmable console. First, it has a 7.5″ LCD with an LED backlight and significant 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, two custom user programs, 1 HRC program, and the manual program. The 30 preset programs cover workouts of all kinds, including an intense burn, stamina, or intervals of high card. The two user programs give you the possibility to create your custom programs.

The HRC program allows you to select a determined HR interval, and the machine will adjust the speed 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 are either metric or English units. A race track function displays the distance traveled as a 1/4 race track for distance, 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 to track your progress better.

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.

TRX4500 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 precise assembly instructions, and an essential toolkit is also (included) with the treadmill.

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 dragged into the motor or the rollers.
