         Our Rating: 4.7/5



LifeSpan’s top-end residential treadmill, the TR5500i is a juggernaut of a treadmill with a not completely out of reach price tag.

Combining excellent build quality and technology with a superb lifetime motor and frame warranty, this treadmill, reviewed below, should be on any runner’s shortlist.


Build Quality

LifeSpan is a health brand that crafts treadmills to protect their customers with both operative safety and long term durability. The marriage of these two attributes prove invaluable if you’re a fitness fiend looking for treadmill power that can keep up with you consistently pounding the proverbial pavement from your home gym.

Their top selling home treadmill (for a reason), the LifeSpan TR5500i Folding Treadmill grants the motor strength needed to encourage you to go farther. Made with the best residential treadmill motor you could ask for, the TR5500i Folding Treadmill’s continuous duty DC drive motor gives you 4.0 HP that will work in tandem with your tenacious workout. With a whopping .75 more motor horsepower than the LifeSpan TR4000i, the TR5500i Folding Treadmill is the absolute top of the line home treadmill LifeSpan offers.

This model has a leg up on its cheaper LifeSpan siblings in a number of ways, from its heightened speed range of 0.5 mph-13.5 mph, boosted weight capacity of 350 pounds, and all-steel frame build.

The TR5500i’s frame is not only strong, but also thoughtfully crafted for an incredible user experience, is the unique isolated design which steadies the treadmill deck as well as the console in an independent fashion, resulting in extreme reduction of treadmill vibration. This reduction of typically frustrating reverberation ensures not only a smoother exercise experience, but also the prevention of shaky entertainment, as regardless of how hard you’re running, the media console won’t be affected.

Preventing you further from having workout limitations is the magnificent decline feature, which allows you to decline the TR5500i Folding Treadmill 2%. Having declining ability is essential to a more well-rounded workout, as it functions to better emulate road running; despite being inside, your body will believe it’s in the great outdoors with this treadmill’s fluctuating ability. Widespread levels of -2 decline up to +13 incline give the TR5500i treadmill an expansive range.

Furthermore, this treadmill’s 22” x 60” running surface is five inches longer and two inches wider than the space available on the more expensive the LifeFitness F3 Folding Treadmill. Lightening not only the load on your budget but also your body strain are the 8 independent compression shocks present within the densely sturdy 1” Phenolic treadmill deck. The EZfold technology paired alongside the two rear mounted and two front mounted wheels makes putting this treadmill away easy as Sunday morning.

With husky strength in both construction and motor, yet simple storing and FCC safety certifications to affirm it’s a gentle giant safe to have in your home, the LifeSpan TR5500i is an agreeable buy for anyone regardless of how hard you exercise.



The TR5500i Folding Treadmill has just the right amount of tech to ensure an enjoyable and easily accessible workout.

Making your fitness fun, the integrated bluetooth with audio playback lets you whistle while you work as you can freely sync up your favorite songs to the audio center, which boasts dual bluetooth speakers. If you’d rather hear voices speaking than singing, you can opt for podcasts or streaming your favorite TV shows through your smart device of choice, which you can conveniently place on the conveniently located media holder.

While you worry about nothing but getting your entertainment on, let the gorgeous full color 10” touchscreen do the work of tracking your effort. The cunning smart technology will keep you accurately abreast of every step you take through Intelli-Step so you can say sayonara to that clunky pedometer. Meanwhile, the contact heart rate sensors will let you in on your percentage max heart rate and heart rate in general.

What makes the TR5000i Folding Treadmill’s tracking advanced is how it can calculate how many laps you’ve taken as well as your split time, making it quite beneficial for competitive runners hoping to outdo their greatest performances. Built for competition, the LifeSpan TR5500i Folding Treadmill comes packed with unique workout programming such as the Navy Fitness Test, RockPort Fitness Test and a 5k or 10k race.

If training isn’t your thing but overall wellness through non-competitive activity is, the TR5500i folding treadmill comes jam packed with over 50 different accessible workouts that will keep your body guessing. Should you rather do your own thing, the opportunity to create and save your own custom workouts will stimulate your interest. Prefer personalization? The TR5500i has you covered all the more as you can choose which of their display options jives best with you. Three alternating viewing options, track view, gauge view and graph view, allow you to tailor the dashboard to whatever best suits your needs.

Should you prefer to take these old school for a bit, the five QuickSet incline and speed buttons located beneath the vibrant console will have you customizing your workout without navigating the touchscreen. Another great feature is LifeSpan’s Intelli-Guard technology, which doubles down on safety by automatically bringing the treadmill belt to a halt within 20 seconds of you stepping off it. We love this as it comes in handy for user protection.

Something else fancy and fabulous about the TR5500i Folding Treadmill is that it is the only LifeSpan residential treadmill that has a cooling fan. The 3-Speed cooling will wick that sweat right off of, keeping you from having to lug in that hefty (and probably dusty, let’s be real) bedroom fan.

When it comes to technology, the TR5500i Folding treadmill is further unique to the cheaper TR4000i model as it has a 3” larger screen, validating that this treadmill truly is worth the additional price tag.


Price Point

When it comes to motor power and strength of build, the LifeSpan TR5500i Folding Treadmill has it all. The incredible construction of the 4.0 HP continuous duty DC motor affirms its muscle in easily accommodating a four person active household, or more!

When pondering price, it’s important to factor in usage and whether or not this has the potential of being a one-time investment. Thankfully, due to incredible motor and frame warranty coverage, detailed below, you can rest your weary head knowing the LifeSpan TR5500i Folding Treadmill was built to truly last.

While NordicTrack is a popular fitness equipment brand, it’s essential to recognize that their treadmill provides extremely weak warranty coverage, which makes you wonder if the hype of their competing treadmills, such as the T 9.5 S treadmill, is worth the cost long-term.

While with that specific treadmill you do get 4” of additional screen size and the ability to live stream workouts on the treadmill itself, if you want to access their higher end technology, you’ll be paying a yearly membership for it. Furthermore, the T 9.5 S treadmill has 0.4 less horsepower, no decline ability, as well as a lower top speed and incline range. While you would think this type of lacking would come at a cheaper cost than the LifeSpan TR5500i treadmill, it’s actually more expensive, which puts how well-priced the TR5500i is into perspective.

When it comes to treadmill research, it’s important to see the contrasting strengths and weaknesses different brands provide before you select one. In the case of NordicTrack versus LifeSpan, you’ll be paying more for a larger screen size and less long-term warranty coverage.

The TR5500i Folding Treadmill is the most expensive residential treadmill LifeSpan offers, and for good reason because it has the power, unique workout programming, tracking, safety features and warranty protection to back up its price.


Pros and Cons

Delving into the LifeSpan TR5500i Folding Treadmill confirms our belief that it is an active family friendly option that meets the safety and high usage capacity expectations a trusted treadmill should provide.

However, we do like to give our readers something to think about; one thing that may not be so transparent when simply looking at LifeSpan treadmill specs online is that when folded, the height of the TR5500i treadmill increases by ten inches. If you’re planning on storing the TR5500i often, this taller discrepancy can be frustrating if it inhibits your view of, say, a TV.

If the added folded height is a viewing obstruction concern for you, it’s best to opt for the LifeSpan TR3000i treadmill, which was designed specifically to minimize treadmill height when folded. That being said, you will sacrifice in features and motor power in the process.

Outfitted with 3 additional screen size inches over the TR4000i, the TR55000i folding treadmill is an eye-catching option made for those who really want to take in the full-color touchscreen display. The higher speed range of 13.5 mph allows you to truly push yourself to hit higher-pace goals, unlike other treadmills, which usually only go up to 12 mph.

Should you believe in the LifeSpan way of treadmill construction, and for record, we do, you can also upgrade to one of their commercial-grade treadmills. The more expensive TR6000i Light Commercial Treadmill, while holding .75 less HP than the TR5500i, is constructed in a way that is focused on longer run-time use.

While the TR5500i treadmill is a great match for high user households who enjoy fast workouts, the TR6000i is wonderful for marathon users hoping to reduce overall treadmill wear and tear during their long runs. While this poses a lot to consider, it affirms the introspection that treadmill buying is truly a personalized choice as the intent of usage varies drastically.

Warranty and Guarantee

If you want to understand how much a brand trusts in the products they produce, a great first step it to look into the included warranty coverage. A willingness to stand behind the product in the form of a solid warranty reflects the trust brands have in their products to actually last.

LifeSpan meets the moment of long-term protection as it offers a lifetime warranty on both the continuous duty DC motor and treadmill frame, which is all steel. Five years of parts coverage provides foreseeable replacements should they be required while two years of labor beats the industry’s typical one year offer.

If you’re looking for an area of lacking when factoring in the TR5500i Folding Treadmill, the warranty coverage isn’t it.


Summing Up This Review
