Introduction

Drop weight while watching HDTV! The durable NordicTrack X15i Incline Trainer leads an impressive collection of powerful treadmill alternatives.

Incline training is an ideal way to rev up your metabolism and the X15i offers a dramatic 40% maximum slope. It also has a max 6% decline to help you improve balance and develop exceptional muscle tone.

Equipped with everything from iPod-compatible speakers to a 15” television, this fitness machine is a top contender for shoppers with comfortable budgets. The X15i Incline Trainer has a $2,999 sale price and carries NordicTrack’s best warranty.

Designed to fit almost anyone’s physical requirements, the X15i has the force to power heavy workouts — its motor has 4.5 continuous horsepower — and provides a spacious 22″ x 60″ surface for walking or running.

This trainer has a 350-pound user weight capacity.

Workout Programs

NordicTrack fitness machines take the guesswork out of training. The X15i’s 44 built-in programs were designed by a certified personal trainer to help users focus on calorie burn, heart rate control, incline training and speed training. Each workout program can adjust the machine’s speed (maximum 12 mph) and angle its track between -6% and 40%.

For literally infinite workout variety the NordicTrack X15i is iFit-enabled too. With a monthly or yearly iFit membership you can access an extensive online selection of video workouts, download a customized workout whenever you’d like, or use the interactive Google Maps™ feature. iFit’s Google Maps™ integration lets you specify any real-life route and virtually experience its terrain: The incline trainer will adjust its incline to simulate the rise and fall of the actual landscape, and a Google Street View will be displayed for a visually immersive workout experience.

For its heart rate control workouts and general guidance, the X15i gives two options for heart rate monitoring. It has CardioGrip™ pulse sensors on its handlebars and arrives with a chest strap for wireless data transmission.

Incline Trainer Features

The X15i has NordicTrack’s top components for durability (i.e., a two-ply tread track, large track rollers and their top motor). It’s also equipped with the brand’s best features for workout support and entertainment.

For performance its distinguishing feature is the dramatic 40% incline. Use the incline to focus on specific muscle groups and burn calories at up to five times your usual rate! For added muscle toning a 6% max decline is provided too. You can make the most of the incline/decline with Google Maps™ workouts, which are available with an iFit membership.

For entertainment the 15″ HDTV is key. This feature isn’t available on any other NordicTrack incline trainer for 2016.

Other perks for digital entertainment are an iPod-compatible port and 3″ speakers, a 10” touch screen with Android browser, and a bracket for your tablet computer. The bracket has an adjustable angle to help people of different heights get a good view.

To promote endurance two AutoBreeze workout fans are built into the console. AutoBreeze fans can automatically adjust their speed to suit your workout intensity. If you’d rather set the speed though, that’s an option too.

Finally, OneTouch controls make adjustments easy. You can change the X15i’s speed and incline without scrolling through menus.

The NordicTrack X15i Incline Trainer has the brand’s best warranty:

– Frame: Lifetime
– Deck: Lifetime
– Motor: Lifetime
– Parts & Electronics: 6 Years

Conclusion

In our review the NordicTrack X15i Incline Trainer is a top treadmill alternative in its price category. It delivers rapid results, is built with durable components and offers more motivation than you’ll find anywhere else. If it fits your budget, go for it! If you’d be wise to cut costs though, then forego the HDTV and opt for the very similar X11i instead. Both of these top incline trainers are crowd pleasers.
