Nautilus Inc. has been one of the world's leaders in gym equipment for more than 30 years. Nautilus treadmills are used the world over in both commercial and home gyms. Typically the treadmills are sold under different brand names since they own many subsidiary companies, one of which is Stairmaster. The Nautilus name, however, is still the primary name for commercial treadmills.
No matter which Nautilus exercise equipment you use, they all come highly reviewed as they all are manufactured with the highest quality. Of course, since Nautilus is such a recognized name, you may pay a little more but most customers will say that it is worth it.

Like most treadmills, Nautilus treadmills come equipped with standard features such as heart rate monitors, some of which have wireless chest straps which are great if one does a lot of running and doesn't want to feel like they are on a leash. They also come with up to 12 different built-in workout programs and 3 custom workouts so you can build the workout that suits you best. They also offer up to a 15% grade, which is fairly typical on commercial treadmill models.

There are a few things that make Nautilus treadmills stand apart from the competition, however. They come with a powerful motor – up to 3.0 hp which allows for a great cardio workout running up to 12 mph. Since Nautilus treadmills are built for great workouts, they are built with a heavy duty frame and claim that they have one of the largest workout areas on the market. This feature is perfect for someone who is taller or has a long stride while running or walking because it won't make you feel like you are going to fall off the end of the machine.

If you are looking for a machine that will stand up to heavy duty use, the Nautilus treadmill is a great option.
