The Open Road Has Met Its Match
The robotically-welded, all-steel frame is precision-engineered to simulate real-world conditions over miles of use, while the 20 by 60 inches running surface perfectly handles your favorite style of exercise. 8 compression shocks provide endless comfort for your knees, back and joints.
Effortless EZFold Technology
The effort stops the moment your workout is over. Simple to lift and easy to lower, the TR4000i’s EZfold technology utilizes a hydraulic shock to assist in folding and unfolding the treadmill. Simply lift the deck for a compact storage position, and when you’re ready, the soft-drop system supports the complete weight of the treadmill as it unfolds for safe, convenient use.
A Treadmill You’ll Never Outpace
The TR4000i comes with 21 easy-to-use exercise programs. Designed by exercise physiologists to expedite your progress, these safe, effective regimens help to improve your cardiovascular fitness, boost your health, and burn fat. Console readouts include: time, calories, distance, steps, heart rate, speed, incline level, pace, and elevation change.
The Open Road Has Met Its Match
The 3-speed cooling fan, guided console navigation, built-in safety features, and patented step-counting abilities make the TR4000i a force to be reckoned with. Intelli-Step, the most accurate step-counting feature available, records every stride you take, perfect for walking competitions and daily goal management. And because nothing is more important than your safety, Intelli-Guard, a patented LifeSpan feature, ensures user protection by automatically pausing belt motion 20 seconds after you step away from the treadmill deck.

The NordicTrack Commercial 1750 makes a repeat showing as our best overall treadmill because it is loaded with desirable features designed to make your fitness routine enjoyable.
It helps you achieve a natural stride and comes with a one-year NordicTrack iFit membership that includes iFit Coach, iFit data tracking and the ability to interface with Google Maps to simulate a run anywhere in the world. This high-performing treadmill has a powerful yet quiet motor and a 22-inch by 60-inch running surface. Its 2.5-inch rollers are balanced and precision-machined, and it has a two-ply commercial grade belt. It can accommodate users weighing up to 300 pounds and features NordicTrack’s adjustable FlexSelect deck cushioning. Deck cushioning is important because it helps protect your joints from injury during workouts.

The 15 percent incline and 3 percent decline add terrain-matching intensity to your workout, and you can exercise at speeds up to 12 mph. This is the most common maximum speed among the machines we reviewed. Like other top treadmills, it includes an EKG grip pulse and a wireless heartrate monitor, and you can track your workout with 11 data points such as time, speed, calories burned and distance.

A treadmill’s running surface is important to helping you maintain a natural gait. Most machines we reviewed have 22-inch-wide belts, so this one can be less comfortable for larger users.

It boasts 21 preprogrammed workouts for weight management, healthy living and sports training and has a maximum user weight of 350 pounds. The treadmill weighs 226 pounds and is the lightest machine we reviewed. It also has an EZfold hydraulic folding system and four mounted wheels for easy moving and storage. Treadmills are bulky machines, so these are especially nice features. This treadmill’s console has a 6-inch blue backlit screen. If you’re looking for a more robust display, we’ve reviewed some machines with larger, full-color displays.

It has a three-speed cooling fan, speakers and an audio-in jack, along with a USB port. Its console readouts give you nine points of data, such as time, distance, steps, pace and elevation change. If you step off the deck for more than 20 seconds, the belt will automatically pause, which is a unique, useful safety feature. Customer service is available by phone, chat and an online contact form. LifeSpan offers free standard delivery.
It provides excellent connectivity for up to four users, and it’s easy to fold up and stow. It has a 4.0 continuous horsepower motor and a 22-inch by 60-inch running deck that can accommodate users who weigh up to 400 pounds. Keep in mind that manufacturers recommend selecting a machine with a weight limit 50 pounds higher than the heaviest user’s weight. Like all the treadmills we reviewed, this machine’s maximum incline is 15 percent. Its console has a 9-inch full-color display. It gives you more workout feedback than any other machine we evaluated, including data such as calorie burn rate, heart rate zone, intervals, distance and speed.
