Frame construction

The Tru Grit curved manual treadmill is built like a tank. It is a super-heavy piece of equipment. Its net weight is approx. 415 lbs (118 kg), so the transport of the packaged unit requires at least two people. However, once it is assembled, it can be moved by only one person. The front section of the base frame features a set of wheels, while the rear base section of the machine integrates a large handle that allows you to lift it with ease.

Most of the machine’s weight is in its deck, so it has a pretty low center of gravity. This leads to a lot of stability. You can be sure that it won’t wobble even if you run at your top speed. The base frame also has adjustable levelers so you can perfectly stabilize it on any type of floor.

Needless to say, most of the machine’s frame is made of steel. The top frame section with the handrails and most other visible steel parts features a durable, double-coated paint finish. Some of the inner steel parts are not painted but made of stainless steel.

The treadmill also integrates several plastic parts. But most of them have only a cosmetic or protective role. Thus, they don’t reduce its overall sturdiness in any way. These are also black, to match the rest of the machine.

The fully assembled unit is fairly large. It is approx. 79″ (201 cm) long, and 35″ (89 cm) wide, while its highest point is approx. 60″ (152 cm) above the floor. It is also recommended to allow at least two feet of clearance on each side and at the rear of the deck for easy access and safe usage. It’s also important to mention here that this treadmill is not foldable.

Deck construction

Similar to the Assault AirRunner treadmill, the Tru Grit RUNN1000 is equipped with a crawler belt that consists of multiple segments. The belt passes over a set of ball bearings and wheels attached to the inner sides of the deck. The belt is pretty thick, durable, and has reinforcement layers on each side. It actually comes with a lifetime warranty which pretty much means that it can take quite a beating.

The deck of the Tru Grit treadmill does not integrate a cushioning system like most motorized treadmills. However, due to the curved design, and the slightly higher front section, the drop of each footstrike is minimal. This reduces the impact on your joints and back by a lot. It also provides a natural and more comfortable motion than a treadmill with a standard flat running surface.

The side sections of the deck are pretty wide as well. They feature thick sheets of rubber material with a textured to in order to prevent foot slippage.

The machine offers a pretty wide running surface. Its belt is approx. 62.5″ (159 cm) long, and 19″ (48 cm) wide. This being said, it should be able to accommodate users up to 6’5″ (196 cm) with no problem, allowing a complete range of motion. Also, the deck has a super sturdy construction. It is rated for a maximum user weight limit of 400 lbs (181 kg).

Unlike regular motorized treadmills, the Tru Grit RUNN1000 has a pretty high running surface. Its front section is at approx. 20″ (51 cm) above the floor, while the mid-section is at approx. 18″ (45 cm). Therefore, it is recommended to use this treadmill in a room with a ceiling that is at least 30″ (76 cm) taller than your own height.

Resistance system

The Tru Grit RUNN1000 is a manual treadmill. In other words, it is not equipped with a motor and does not require an external power source. The only power source required for it is a set of batteries for the fitness monitor. The belt is powered by the user and always adapts to the running or walking speed of the user.

The machine is equipped with a manual magnetic resistance system. This particular resistance system is similar up to a point to the resistance of an exercise bike. It consists of a thin, internal flywheel and a magnetic brake that hugs this flywheel. The brake connects to the tension dial on the right handrail through a steel cable. Therefore, when you increase the resistance, the magnets will hug a larger portion of the flywheel.

The treadmill makes available 6 tension levels. On the lowest setting, you will basically run or walk with no additional tension. The 6th tension level adds considerably more resistance to the belt which enables your walking or running to feel like your going up hill, or like you’re pushing a sled.

It’s important to mention, though, that the machine’s resistance system is full-manual. The tension of the belt can only be adjusted from the dial. The fitness monitor plays no role in the resistance adjustment, and you cannot sync the resistance level with it for a more precise calorie reading.

Fitness monitor

The Tru Grit curved manual treadmill is equipped with a pretty basic fitness monitor for a machine in this price range. It does not have pre-set programs. It does not have Bluetooth or wireless connectivity. It isn’t compatible with any fitness apps. It also does not have a pulse reading function and the machine does not integrate pulse sensors.

The fitness monitor features an LCD display divided into 5 sub-sections so you can view up to 5 workout metrics at once. It tracks time, speed, distance, calories, and pace. Speed and distance are shown in British Imperial units (MPH and miles). There is no option for changing them to metric units.

The monitor unit does not have HIIT interval programs. However, it does offer the possibility to select workout goals for time, distance, and calories. If a goal is selected for any of these, the monitor will count down from the selected value until it reaches zero.

The monitor unit is pretty easy to use. It has three buttons: Reset, Mode, and Set. The Reset button allows you to clear all the values on the monitor to zero. The Mode button covers the selection function. And finally, the Set button covers the goal creation function.

The unit is battery-powered. It requires two AA batteries. It starts up when you press the Mode button. It automatically turns off after a few minutes of inactivity on the treadmill. It also integrates a small shelf that can serve as a tablet or phone holder.

Assembly and Maintenance

The base of the treadmill comes pre-assembled. You only need to attach the upper frame pieces and the fitness monitor. This shouldn’t take more than 30-40 minutes of your time. The manual provides clear assembly instructions and a basic toolkit is also included.

For maintenance, you only need to keep the machine clean, especially the belt. The inner ball bearings on the belt’s tracks are pre-lubricated and the belt itself does not require lubrication. It’s also recommended to periodically inspect the machine, to make sure there are no loose or broken parts.
