The ProForm 6.0 RT is a walking/jogging treadmill made for home use. It’s also in the affordable category, as it costs less than $400, at least for the moment. It’s definitely not a treadmill with all the bells and whistles, cannot be compared with a commercial grade model, such as the ProForm Boston Marathon 4.0 or the Body-Solid Endurance T100. However, it still does offer more than other models in this price range, as it has an automatic incline system and a decent array of pre-set workouts.

To be more specific about the identity of this product, this is the ProForm PFTL39115 model; it’s also referred to as the ProForm 6.0 RT Crosswalk Treadmill, as it’s the one equipped with a set of resistance cords, and as opposed to the PFTL39511, it has 16 onboard workout programs, rather than just 8.

Frame and deck

The construction of this treadmill is very much similar to the ProForm 300i model. It has the same dimensions and the same deck build. It’s not a large treadmill compared to others, featuring a footprint of 65″L x 29″W (165 x 74 cm). However, just as any other proform pftl39115 6.0 rt - folding frametreadmill, you should leave at least three feet of clearance at the rear of the deck, and at least two feet of clearance on each side, for unhindered exercising. But nonetheless, the machine’s deck can fold up, connecting to the left upright mast. With the deck folded up, its length is reduced to 26″ (66 cm).

Even though it’s a treadmill for light workouts, it is built around a steel frame. The base of the frame which incorporates the deck features a black finish, while the upright console masts are white. The finish on these metallic parts is a highly resistant to corrosion powder coating. The front base of the frame is equipped with a set of wheels to facilitate the machine’s relocation, once it’s fully assembled, and with the deck folded up.

This ProForm treadmill only offers a running surface of 50″L x 16″W (127 x 41 cm). This pretty much means it’s a treadmill for crosswalk or light jogging. Taller users, over 6’2″ (188 cm) will find its running area too small for running; however, walking shouldn’t be a problem. Also, this machine is rated for a user capacity of 300 lbs (136 kg), but this user capacity refers only to crosswalk workouts. Running workouts are not recommended to users who weigh more than 175 lbs (80 kg).

The ProForm 6.0 RT treadmill is equipped with a heavy-duty, 1-ply belt, strong and flexible to reduce power consumption. The belt is low-friction, low-noise, and comes pre-lubricated from the factory. It rolls over 1.9″ balanced and precision machined rollers with sealed, stainless steel ball bearings, designed to last for many years of use. The deck also integrates two ProShox cushioning cells (one on each side), which absorb up to 20% of the walking impact, rendering your workouts friendlier to the joints and lower back.

Since it’s a crosswalk treadmill, it is equipped with two elastic cords with ergonomic handles, attached to the lower end of each console mast. These cords considerably diversify your workouts, allowing you to perform a variety of exercises for toning your arm muscles and for increasing the amount of calories burned. The resistance of these elastic cords is adjustable. You can increase the tension that they generate by reducing their length, moving their stopper collars.

One last aspect to mention here regards the machine’s weight. Even though it’s a rather small treadmill, it does weigh over 150 lbs, delivering excellent stability.

Incline & step-up height

The motorized incline system of the ProForm 6.0 RT is one of the aspects that place this particular treadmill above basic models. Other walking treadmills in this price range do not have an incline at all. Or, they’re equipped with a manual incline system, such as the Sunny SF-T7603.

The incline mechanism is situated at the front of the deck; it involves a small lever which will elevate the front part of the deck by several inches. It can actually generate a slope of 10%. The incline can be adjusted in increments of 1%. The control unit features incline controls for quick adjustment (from 1 to 10) and gradual adjustment.

The deck’s step-up height is approx. 7″ (17 cm) at 0% incline, and will raise by a few inches when the incline is set at 10%. Therefore, make sure that the ceiling height in the room where you will be using this machine, is at least 12-13 inches higher than your own height.


As we’ve mentioned above, the ProForm 6.0 RT is a treadmill designed for crosswalk. It is, however, equipped with a 2.0 CHP motor, which can generate running speeds up to 10 MPH. It’s also a continuous duty motor which performs excellently even during prolonged workouts, without overheating or choking.

The starting speed of the belt is 1 MPH. The console allows the speed adjustment in increments of 0.1 and 0.5 MPH. The + / – speed adjustment keys have dual-functioning; a short press of one of these keys will adjust the speed of the belt by 0.1 MPH, while a long press will change the speed in 0.5 MPH increments. This is actually quite a plus, as you can easily find the pace that fits perfectly to your workout. There are, of course, keys for quick speed selection, from 1 to 10 MPH.

Evidently, since it’s a motorized treadmill, it requires being connected to a power circuit. It comes with a classic U.S. plug and requires 120 V AC 15 amps power circuit. The power cord connects to the machine near the front base, where the motor is located.

Control unit

The control unit of the ProForm 6.0 RT treadmill is a lot similar to the one of the 300i model, but it’s not iFit or Bluetooth enabled. It does offer 16 pre-set workouts, though, divided into two categories, 8 Weight Loss Workouts, and 8 Performance Workouts. Byproform 6.0 rt crosswalk - console using one of these programs, the belt will auto-adjust its speed, and some of them will also automatically adjust the deck’s incline. Of course, there’s also the Manual Mode which basically gives you the possibility to adjust speed and/or incline as you like, during your workout.

The console integrates a 4″ LCD display, which can track values such as distance, time, calories burned and pulse. It also displays the selected belt speed and the current incline. There’s a track function which can display distance in laps of 1/4 miles (400 m), indicating your current progress for each lap, and keeping count of your completed laps. You can setup the unit to display the distance traveled in miles or kilometers, while speed can be calculated in MPH (by default) or km/h. Pulse rate can only be measured via the sensors in the machine’s front handlebars. The console unit is not telemetric.

The operation of the control unit is simple and straightforward. As we’ve mentioned above, it features + / – keys for gradual speed adjustment, and arrow keys for gradual incline adjustment. However, there also are keys for quick incline and speed selection, from 1 to 10. The preset workouts are divided into two categories, “weight loss” and “performance”, each category having its own key on the console. Manual mode has its own key as well. Also, there’s “STOP” button which gives you the possibility to put your workout on hold, in case you need to interrupt it, or in case you’re alternating treadmill sessions with other exercises.

The console integrates a basic sound system, compatible with most smartphones, tablets and MP3 players. You can connect your device and listen to your music through the speakers of the console, speakers that offer a better sound quality than the speakers integrated into phones or tablets. To connect your device to the console, you’ll need a cable with a 3.5 mm jack, cable which is not supplied. There are no keys for volume adjustment on the console; sound volume can only be adjusted from your device. The console dashboard also features two molded trays to serve as support for small accessories.

Assembly and Maintenance

The ProForm 6.0 RT comes partially assembled. Its deck, motors, tread belt, and rollers are already assembled and attached to the lower metallic frame. Therefore, you only need to attach the upright masts and connect the console, aspect that shouldn’t take more than 30 minutes. Two hex keys are supplied for assembly and belt adjustment, but you’ll also need your own Phillips screwdriver and needlenose pliers. The whole assembly shouldn’t take more than 30-40 min.

Maintenance doesn’t require much. Like most treadmills, the belt requires being lubricated after several months of use. The belt on this treadmill comes pre-lubricated with industrial quality lubricant, though, and should only require further lubrication after several months of use.
