Our Rating: 4.6/5
The cheapest true running treadmill of LifeSpan’s lineup, the TR4000i is a high performance treadmill with some unique features at its price point.
In this review, we’ll delve into why this treadmill is worthy of its nothing to sneeze at 4.6/5 star rating.
When buying a treadmill, many don’t realize that if you’re a runner looking to pick up the pace for years to come, the majority of easily marketable treadmills don’t actually hold enough motor horsepower to meet your needs. Buyers can get fooled by looking at the speed range of a treadmill, thinking that if it goes as fast as they want to, it meets their needs.
That being said, it’s the horsepower the motor packs that reflects what type of activity a treadmill is best suited for; just because a treadmill can go faster, doesn’t mean it should. If you’re a runner looking for treadmill that will last a long time, getting a higher horsepower motor greatly enhances the life of your motor as well as wards off breakdowns, repairs, and the worse case scenario: having to buy a whole new one altogether.
Plain and simple, consistent running on a treadmill requires a motor strength above three horsepower. Created specifically for ardent runners, the TR4000i Folding Treadmill comes packed with a 3.25 HP continuous duty DC motor that packs enough power to meet your runs, wherever you want to take them.
Not only is the horsepower provided by the TR4000i adequate, the continuous duty motor build is the most dependable you can find for a home treadmill. Don’t believe us? Just look at the lifetime warranty LifeSpan offers on the TR4000i treadmill motor.
While you can rest easy knowing your treadmill motor can keep up, extending your peace all the more is how the LifeSpan brand builds their products with safety at the forefront of their mind and the TR4000i Folding Treadmill has the certifications to prove it. Giving you peace of mind when it comes to exposing your household to fewer electromagnetic fields and radio frequencies, the FCC certification assures the TR4000i treadmill has been tested to fit beneath the government’s safety limits. Adding to the user protection are the non-slip plastic side rails, which allows safe space for you to rest while you stop or start the treadmill.
Making this model incomparable to lower in class LifeSpan treadmills, such as the budget-option TR12000i Folding treadmill, is its decline feature, which better simulates an outdoor workout. A wide range of a 2% decline to a 13% incline will have your body forgetting its moving inside and feeling as if it’s out and about, taking on the world around you like the road runner himself. This LifeSpan model will meet the high expectations of both fiery fitness and safety gurus alike.
LifeSpan, while known for their safety and quality, aren’t as top-notch when it comes to technology like other brands, such as NordicTrack. However, with the TR4000i Folding Treadmill, Lifespan has stepped it up a notch when it comes to added tech features.
Newly designed in 2019, the smart, full-color touchscreen display offers 7” of intelligent beauty and reflects just how tuned into your workout the TR4000i folding treadmill is. To best accompany the 2% decline and 13% incline range, LifeSpan created a plethora fierce workout programs, crafted by sports psychologists to emulate an outdoor exercise experience.
From the comfort of your cozy home, you can feel the burn by selecting from the following programs: RockPort Fitness Test, Navy Fitness Test, seven different sports training options, a 5K or 10K race, five separate weight management exercises, and five altering healthy living programs. In addition, you can personalize your favorite movement set with two distinct customizable workouts as well as two differing heart rate programs.
When tallied up, the TR4000i Folding Treadmill provides over 50 preset programs that will keep you shocking your muscles for years to come. For reference, competitors such as the Life Fitness T3 treadmill only provides 14 workouts, no decline feature and no touchscreen, and will have you paying nearly a thousand dollars more, making the TR4000i Folding Treadmill an absolute steal when considering features.
Amplifying the exercise features all the more is the detailed activity tracking the TR4000i Folding Treadmill’s touch screen display communicates to you in full color. We’re not just talking the average readouts such as heart rate, pace, speed, calories burned, distance and time. Rather, we’re referring to the TR4000i’s tracking of the total laps and split time, total steps per minute, change in elevation and percentage max heart rate.
Furthermore, premium sound dual speakers paired with built-in bluetooth connectivity will have your favorite music, podcasts or streaming show pumping far beyond the small speakers within your smart device. The focus of user-protection is further affirmed by LifeSpan as the patented Intelli-Guard technology will automatically halt belt movement for 20-seconds should you abruptly step off to catch your breath or pause your workout.
Track your heart rate thoroughly with the contact heart rate sensors, located conveniently onboard. Promoting accessibility all the more are the five QuickSet incline and five QuickSet speed buttons, which prevent you from having to navigate the touchscreen mid-workout.
This treadmill was designed to compliment the technology available within this new decade, meaning you can file concern of an outdated treadmill away in your mind for a long time.
The price point of the TR4000i Folding Treadmill is insanely reasonable when you consider its 3.25 HP continuous duty DC drive motor and the versatility of muscle group targeting the decline ability provides.
Not to mention, the vast options provided with the workout programming alone are notable. The TR4000i treadmill’s over 50 workout programs make competitor treadmills, such as the Sole F80 treadmill, which comes in at the same price but only has 10 preset workouts, pale in comparison.
Furthermore, the NordicTrack T 8.5 S will cost hundreds more and will provide less incline, smaller treadmill rollers, a deflated warranty, no decline ability, and require an annual subscription for live workout classes. That being said, the NordicTrack T 8.5 S does provide 50 onboard workout programs and .25 more motor horsepower in addition to it’s 10” Smart HD touchscreen, which is 3” larger than the LifeSpan TR4000i Folding Treadmill’s full-color touchscreen display.
If you can afford the cost of the NordicTrack T 8.5 S, but want the build quality LifeSpan provides, it’s worth considering the top-of-the-line TR5500i treadmill, which comes with a 4.0 HP drive motor.
Setting you back under two-hundred dollars more than the lower in class LifeSpan TR3000i, the TR4000i treadmill takes motor power from 2.75 hp to 3.25 hp, making it the far better option for those looking to run. Meanwhile, the boosted workout programs and decline feature are far better suited for workout buffs really trying to make a visible difference in their body by opting for more overall variety.
However, if you’re not into outdoor simulation and prefer straight incline, the TR3000i treadmill does provide 2 more incline levels than the TR4000i, making it a cheaper and better-suited option for those interested in walking on heightened incline. That being said, the smaller running surface provided by the TR3000i folding treadmill makes the TR4000i more appealing to those who prefer a roomier ride.
When it comes to the competition, you can exhale a sigh of relief knowing the LifeSpan TR4000i Folding Treadmill has your back as a sound investment. Choosing between which LifeSpan treadmill poses more personal consideration from you as a consumer, however, as only you know just what kind of workout(s) you’re most interested in.
Pros and Cons
The LifeSpan TR4000i Folding Treadmill doesn’t give us too much to complain about as it really isn’t a treadmill that lacks. Considering it has an insanely trustworthy build, holds a continuous duty DC motor, offers a large 22” x 60” running surface, a 2.8 mm thick running belt that boosts durability, and a lifetime warranty on the motor and frame, this treadmill is a truly a great choice for the price.
If you’re into live streaming workout classes and prefer not to use your tablet to access them, the TR4000i Folding treadmill is not the choice for you. Rather, if you’re a tech guru and willing to spend more money to quench your technology thirst, look into the NordicTrack T9.5 S treadmill or Life Fitness Club Series + treadmill.
That being said, should you see those prices and realize the TR4000i Folding Treadmill is what would make your bank smile most, then opting for this well-priced treadmill built to last a lifetime is quite the sound choice when it comes to longevity. Making you feel all the more comfortable are the eight independent compression shocks that protect your joints; when paired with the incline and decline capabilities of this treadmill, these shocks work to mimic an outdoor exercise.
The easy folding and transportation friendly treadmill has front and back mounted wheels, making it easy to move and quickly store away. A 1” phenolic deck and large 2.5” front and 2” rear rollers will give you the quiet and smooth ride desired with a home treadmill. After a thorough analysis of this treadmill, it’s plain to see why we have the confidence to say the LifeSpan TR4000i Folding treadmill has far more pros than cons.

Warranty and Guarantee
Perfectly reflecting just how well-built the LifeSpan TR4000i Folding Treadmill is are the two lifetime warranties provided on the deck and motor. Having both deck and motor lifetime coverage is what brands like NordicTrack fail miserably at, even on their most expensive treadmills.

Bringing the LifeSpan back down to earth where its competitors like NordicTrack lie are the average 5-year parts and 2-year labor warranty available on the TR4000i Folding Treadmill. When it comes to coverage, you couldn’t ask for more than what the LifeSpan TR4000i Folding Treadmill has available.
