Frame and Construction
The Nautilus T618 Treadmill Machine is motorized and built like a tank. It possesses a durable heavy-duty steel frame that has anti-corrosion finish, while other parts such as the dashboard, the rails, and the motor covers are made of quality plastic.
Thus, it looks professional and supports a maximum user weight capacity of 350 lbs./158.7 kg.
The base features oversized crossbar tubing, anti-skid rear base, and adjustable rubberized levelers that guarantee superlative stability. On top of that, its overall assembled weight of 285 lbs./129 kg grounds the treadmill like a rock.
Therefore, no amount of aggressive workouts could make it wobble or inbalance.
The treadmill is kind of bulky; it has an assembled dimensions of 78” long by 38” wide by 63” high. Differently put, it’s going to require a workout area with measurements of 6’5” length by 3’2” width and additional extra clearance of 2′ around it for easy access and safety during workouts.
To determine the suitable ceiling height of the room where the treadmill is going to be used, add 18” (maximum incline) to your height and a couple of inches for clearance.
For instance, a 6′ tall user requires a ceiling height of 72” (user’s height) + 18” (maximum incline) + 5” clearance = 95” (7.9”).
The Deck of the Nautilus T618 Treadmill Machine
The step-up height of the deck is 9”, and the wide and textured side rails allow you to quickly exit a workout without having to turn off the treadmill.
The deck incorporates a 3-ply, 2.5mm thick tread belt, and a 2.75” crowned rollers for smooth and quiet rolling motion. Its dimensions are 20” W x 60” L, spacious enough for running activity.
Users can work out without feeling overwhelming stress on the joints because the deck’s rebound cushioning system provides a soft landing for the foot. Hence, it absorbs and reduces the impact.
The Nautilus T618 Treadmill Machine is equipped with a powerful 3.5 CHP motor that provides a speed range of 0.5-12 mph. It supports the demands of vigorous high-speed workouts by a heavy user without breaking down or overheating.
The motor is designated at the front base with a plastic cover, and its operation is vibration-free due to the integrated small flywheel. The noise level of the treadmill is far lower than the noise generated by the footfall during a workout.
Therefore, its operation doesn’t prevent you from watching a movie/TV show or listening to good music while exercising, and neither does your workout activity disturb the family or the neighbors.
The speed can gradually be adjusted by an increment of 0.1 mph or quickly by 2 mph, 4mph, 5mph, 6mph, 8mph, 10mph, and 12mph via the speed buttons on the console. So, walkers and joggers can find a suitable speed range for their workouts, while sprinters can easily select a high speed.
A 120V, 15A power outlet is required for the treadmill to funcion.
The T618 Treadmill has a 0%-15% automatic incline system. This means it consists of a small motor and a lift that raises and lowers the front deck whenever it is adjusted.
Just as the speed, the incline could be adjusted gradually by an increment of 1% or quickly by 0%, 2%, 5%, 8%, 10%, 13%, and 15% through the onboard incline buttons.
The combination of a certain incline level and a speed range provides a certain degree of a workout challenge that tones muscle groups and burn tons of calories.
The treadmill features a Bluetooth-enabled console with a DualTrack blue backlit LCD monitor. The upper and the lower display screens are 3.75”, and 5.5” in size, respectively. They provide important information such as Time, Distance/Lap, Heart Rate, Calories, Incline, and Speed/Pace.
The Distance and the Speed values can be measured in miles or km, and mph or km/h, respectively.
These workout data are displayed with high readability that cannot be compromised by a poorly-lit room.
The 26 onboard workout programs include 1 Manual, 3 Goal settings for distance, calories, and time; 4 Custom Programs that allow you to create customized programs that could be used immediately and later; 5 preset Heart Rate Programs that includes <60% warm-up, 50-70% fat burn, 70-80% aerobic, 80-90% anaerobic, and 100% max;
5 Weight Management Programs include fat burn 1, fat burn 2, incline burn, speed burn, and dual burn; and 6 Training Programs that include boot camp, performance, endurance, 1-mile pacer, 5k pacer, and 10k pacer.
4 Users can create a profile that requires the entry of personal information such as age, weight, gender, height, name, and preferred workout value. Each user profile tracks and records the user’s workout progress accurately.
The incline and the speed adjust automatically when any of the preset workout programs is selected.
The Bluetooth technology syncs the treadmill with online apps such as Nautilus Trainer 2, MyFitnessPal, NautilusConnect, RunSocial, and many more via an Android, or iOS-based smartphone.
Any of these apps allow you to track, record, and share your workout progress online. Especially, Explore the World app enables you to travel the world, and run through 19 locations, and 27 routes virtually, and more.
The heart rate data can be read and transmitted to the monitor through the use of the EKG contact grips or wireless HR chest strap (included).
Aside from the workout-related features, the treadmill also has fun related features that help you to enjoy every minute you spend on it.
Such features include the built-in speakers, MP3 3.5mm auxiliary port, a 3-speed cooling fan, a tablet holder, cup/accessory holders, extra accessory rack below the console, and the USB charging port that is also used for transferring workout data to a flash drive.
The Nautilus T618 Treadmill Machine is not compact or lightweight, but it does have a space-saving design and transport wheels for easy storage.
Its SoftDrop system helps you to easily fold and unfold it, thereby reducing the 78” assembled length to 46”. Hence, a storage area with measurements of 3’9” length by 3’2” width can accommodate the treadmill.
