This treadmill boasts a powerful 3.0 CHP Commercial motor and a spacious (20″ x 55″) running surface. What sets the NordicTrack Reflex 4500 Pro apart, however, is the unique “Reflex” cushioning system.

There are 20 Performance Workouts that automatically adjust the incline and speed of your treadmill, each focusing on performance goals. Additionally there are 6 Weight Loss Workouts which have been designed in order to help you burn the maximum number of calories.

The treadmill uses the new iFIT technology to connect the treadmill to the internet allowing you to add interest and functionality to your workout. You can manage your profile online and even work out with Jillian Michaels. It should be noted that this feature requires a wireless internet connection and membership to iFIT.

The console incorporates an attractive display that can show either multiple information fields, for more at-a-glance information, or a single display as large as 1″ tall, for on-the-fly goal training. The console display also features a compatible Music port for use with an iPOD.

The product is endorsed by a Lifetime guarantee on the Motor and Frame, with 2 year of parts and 1 year In-home service.

Here are the main features:

Drive motor

The treadmill utilizes a DurX 3.0 CHP motor. This is a commercial-grade motor that includes high-grade wiring and insulation ratings, and a thermal cut-off switch. It uses commercial bearings and brushes, and is dynamically spin-balanced and extensively tested for superior performance in vibration and noise to make it both smooth and quiet in operation.

Reflex cushioning

This model utilizes NordicTracks’ legendary “Reflex” cushioning system. The main component of this is the deck which is made of a composite construction and is able to absorb impact shocks without sacrificing durability.

The deck has been designed to be both strong and flexible so that it responds to your movement, absorbing impact at the heel and maintaining stability at toe off.

Workout programs

Keeping motivated is an important factor in trying to achieve your fitness goals and having a good variety of workout programs on a treadmill can help with this.

20 pre-programmed Performance Workouts are built in to the treadmill each of which has been designed by a Personal Trainer which automatically adjust the incline and speed of your treadmill. Each of these focus on a different performance goal.

In addition to the Personal Trainer Workouts there are also 6 Weight Loss Workouts which are designed to help you burn the maximum number of calories.

Easy to read display

Depending on the training features available for your treadmill, the Grafixx Display can help you track your fitness history, visually represent your workout intensity or even show you racing against a virtual competitor.

Heart rate monitor

You can get a more effective workout, burn more fat, and improve your cardiovascular health.

Speed control

1-Touch control is used to regulate the speed of the belt. Instead of scrolling through options, the 1-Touch system allows you to instantly change the speed of the treadmill between 0-12 MPH with the single touch of a button. You can decrease your speed immediately when you need a rest, or increase it instantly for a challenging workout.

Incline control

The 1-Touch control technology is also used in order to change the incline. A single touch of a button does the job instead of having to scroll through options as with conventional controls. The incline can be adjusted between 0 deg. up to 15 deg. of grade.

iPOD connection
