LifeSpan TR5500i Treadmill - Best Features

Large Runner's Deck

The TR5500i has a large belt, giving you plenty of room to stretch out during your running workouts.

At 22″ wide and 60″ long, it’s one of the roomiest treadmills you’ll find on the market today, and 2″ wider than the belt on the step down TR4000i model.

This is a great for all users, but especially taller users who may feel a bit cramped on machines with smaller footprints.

Ton of Built in Workouts

The LifeSpan TR5500i has an impressive amount of built in workout programs….43 in all, which is more than you find on most treadmills in this price range.

You get a nice mix of heart rate programs, weight management, healthy living, sports training, as well as specific program for decline training.

With so many workouts to choose from, you’ll never get bored, and this will keep you motivated to reach your fitness goals quicker. You’ll also target different muscle groups and really give yourself a good cardio workout.

Incline and Decline Capability

Rarely do you find decline capability on a residential treadmill, especially one at this price.

The LifeSpan TR5500i has 13 levels of incline and 2 levels of decline, so you can really change your training up.

Incline and decline allow you to hit different muscle groups in the leg than you would with flat training, and provide a more effective cardio workout for you.

Only NordicTrack and Sole offer decline training capability currently.

Bluetooth Tracking Capability

There’s an optional Bluetooth adapter that gives you the ability to track and share your workouts via the Active Trac app. You can then sync your results with your LifeSpan Club account, and keep tabs on your progress.

Workout tracking is extremely popular these days, as it helps keep many people motivated as they set goals for themselves, share results with family and friends, and hit milestones.

You can also use the built in USB drive for workout tracking if you don’t want to buy the Bluetooth adapter.

Note that the popular base model TR1200i is the only one currently without optional Bluetooth workout tracking.

Easy Folding and Unique Design

The 5500i comes with the company’s EZ Fold system, which means you can raise and lower the treadmill very easily. Just lift it up and fold it, and when you’re ready to use it again, just pull it down and it’s ready to go within seconds.

It also has a unique independent support system that you don’t often find, which makes the treadmill much more secure, eliminating the wobble that you sometimes get on similarly priced treadmills.

Other Great Features

The LifeSpan 5500i treadmill also comes with grip and wireless heart rate capability, a cooling fan, music port with speakers, tablet holder, step counter, a powerful 4.0 CHP motor and a 350 lb. maximum user weight capacity.

LifeSpan TR5500i Review - Conclusions


There’s a lot to like on the top of the line LifeSpan TR5500i…things you just don’t typically find on a treadmill under $2,000.

You get a large running deck, a strong motor, good cushioning, incline/decline, tons of workout programs, heavy max user weight and a very strong warranty.

You also have the option to track your workouts via Bluetooth or USB, and there are a lot of unique built in technologies like Intelli-Step, Intelli-Key and Intelli-Guard, all included to enhance your user experience.


Although the TR5500i is just teeming with features, there are a few drawbacks as well.

For starters, although it’s perfectly fine, the blue backlit 6″ LCD display is not as advanced as some of its competitors.

For example, the similarly priced NordicTrack Commercial 1750 has a 7″ touch screen with more advanced capability.

Since the TR5500i is LifeSpan’s top model, it would be nice if it had a standout display. Not a deal breaker, but just something to think about.

Also, we’re not sure why Bluetooth isn’t built into the machine, rather than an available option. With workout tracking being such a big thing these days, you would think their top model would have it standard, as it is on many of its competitor’s treadmill models.

Bottom Line

The LifeSpan TR5500i is definitely a very good choice in the sub $2000 price category. It has just about every single feature and capability you could want, and some things like decline training and safety features that are unique to the company.

Hopefully they will upgrade the console at some point, and perhaps make Bluetooth tracking a standard feature rather than an option.

If you’re looking for something even more advanced, check out the company’s Commercial Treadmills: the TR6000i, TR7000i and TR8000i. These are more club quality, and might be better for very heavy use.

Otherwise, the TR5500i is a very solid option for you.
