Cons / This treadmill does not offer interactive videos or web browsing.
Verdict / The LifeSpan TR4000i has a streamlined design that offers the basics you need in a treadmill, though it's missing some convenient extras.
The LifeSpan TR4000i treadmill is a good example of what a treadmill should be. It has a fine selection of features as well as 21 workout programs. You can customize your exercise sessions, make use of goal-setting programs and track your progress, though it doesn't have the premium extras of the best treadmills.
The TR4000i comes with many notable performance features. The 3.25-horsepower motor propels the belt up to 12 mph, which gives you the flexibility to walk, run or sprint as you train.
The treadmill is also capable of inclines up to 15 percent, which is what the best treadmills offer. A treadmill with incline permits you to train while reducing the impact on your joints and exercising different muscle groups. The maximum weight this treadmill can hold is 350 pounds, which is typical for treadmills.
The standard features on this motorized treadmill are great for everyday workouts. The workout programs emphasize many different fitness goals, such as weight management and sports training. There are also dedicated programs that aid you in reaching and maintaining your target heart rate.
You can sync the treadmill with such popular fitness apps as MyFitnessPal, Up by Jawbone, MapMyRun and Strava. You can use this in conjunction with either an iPhone or Android smartphone. However, if you want to sync this with Bluetooth-enabled equipment, you will need to buy a LifeSpan Bluetooth adapter.
The extras on this running treadmill are basic but still add to your overall exercise experience. The audio port and speakers allow you to listen to your music to stay motivated. Working out this way can be sweaty business, so you undoubtedly will appreciate this treadmill's built-in cooling fan. However, you do not get a touchscreen, interactive workouts or the ability to browse the web with this device – all benefits that higher-ranked treadmills in our lineup offer to add a measure of fun to exercising.
You can easily fold this treadmill when you are not using it and store it conveniently out of the way. It is unlikely you will have to strain to fold or unfold it, since it uses the company's patented EZfold technology. You lift the deck upright to get it into the folded position, and when you want to use it, this treadmill includes a system that supports its full weight as it opens.
The warranty and support options for this treadmill are excellent. You get lifetime coverage for the frame and motor, which is what you would see with the best treadmills. The device's parts and electronic elements receive coverage for five years. The warranty includes one year of coverage for labor.
LifeSpan offers a variety of direct customer support options. Customer service agents are available by phone, email and live chat to help you with general problems. You can download the user manual in a convenient PDF format to have on your computer or smartphone for future reference.
