Good points: This is one of the more durable treadmills manufactured by Nordictrack Superior sound system to other Nordictrack treadmills Reasonably priced for a “commercial” treadmill Large belt combined with a powerful motor results in a good running experience Bad points: Does not support iFit Live, only iFit workout cards We would have liked to see a stronger warranty Comments: Though by no means a true commercial treadmill, we feel the Nordictrack Commercial is a solid and safe choice for your home. This is especially true if you’re not interested in the more extravagant functions such as a built in TV or iFit Live. By cutting out these extra features, the Commercial ZS by Nordictrack can be had for a reasonable when it’s on sale. Another treadmill that we would also recommend you to take a look at is the Nordictrack Commercial 1500. Yes, it’s a few hundred dollars more, but it’s equipped with slightly more features and a more reassuring default warranty. The NordicTrack Commercial ZS treadmill is one workout machine you should try. With its amazing 28 personal trainer workouts which allow you to choose from aerobic, weight-loss or performance goals while automatically adjusting the speed and incline of the machine, you will surely shred those pounds and achieve the body you’ve always wanted. Also included are 4 create and save workout programs for a more personalized workout suited to your needs. To make every workout as intense as possible, the NordicTrack Commercial ZS treadmill has 1-touch speed and incline control to provide you with a 0-12mph speed range and 0-12% machine incline, respectively. This effective workout machine even has the iFit workout card technology that automatically adjusts the speed and incline of the machine while a voice of a certified personal trainer assists you throughout entire workout.
