Nautilus Treadmill Reviews and Buying Guide

Nautilus has been at the top of the fitness equipment industry for over 40 years, and in that time have revolutionized the design of strength and cardio equipment. But to find out whether a Nautilus treadmill is the right choice for you, it’s worth finding out a bit more about the company.

In the first few weeks of 2016 alone, Nautilus, Inc. launched its Bowflex and Schwinn product lines in Europe, Australia, and New Zealand. Not only that, they’ve also acquired another fitness equipment brand in the shape of Octane Fitness, and increased sales by 22% in 2015 compared to 2014.

Nautilus, Inc. is an incredibly strong company that stands behind its brands and continues to grow, which is a reflection of the quality of its fitness equipment. Including its line of home treadmills.

That’s why we wanted to put together a quick guide to our Nautilus treadmill reviews, with a summary of all the best features to help you decide which model is best for your own home workouts.

Why should I buy a Nautilus Treadmill?

Automatically sync your workout data with the MyFitnessPal® or Nautilus® Trainer Apps

As a brand, Nautilus, Inc. has a wealth of experience in the treadmill industry, managing the design and development of its own line of treadmills as part of a wider fitness equipment collection.

They built on this success by acquiring Schwinn Fitness in 2001, who themselves had purchased Hebb Industries and their Trimline treadmill range in 1998.

Nautilus have since taken the knowledge they gained from these existing machines and upgraded the features at all levels, from console functions to the latest performance tracking tech. The result is their T614 and T616 treadmills.

Both machines usually retail for under $1000, which makes their specifications even more impressive. This includes a 12 mph maximum belt speed as standard, 12% incline, touch and telemetry heart rate monitoring, and workout data sync to NautilusConnect.

Features like these are what make the Nautilus treadmills stand out at this price range, even above highly rated treadmills from competing companies like LifeSpan and ProForm.

The 10 year warranty on the frame for each model isn’t quite as impressive as the lifetime warranty offered by companies like Yowza Fitness and Sole, but the 10 year motor warranty is twice the length of most manufacturers.

Schwinn vs. Nautilus treadmills

As you’ll discover in our reviews, the 2015 treadmill collections from Nautilus and Schwinn are incredibly similar. In fact, they’re almost identical.

If you’re interested in buying one of the treadmills below but aren’t sure if a Schwinn model is better, your best bet is to take a look at the SchwinnConnect and NautilusConnect sites for workout tracking.

Base your decision on which treadmill you prefer based on its looks, and which site you find easier to use.

Occasionally there is a significant price difference of $100 or more between the respective treadmills from each collection. In this case your best choice will probably be the one that’s most affordable.

The following is a guide to how they match up:

Note: At the time of writing this guide, the Schwinn 830 and Nautilus T614 are price the same, but the Schwinn 870 is $50 cheaper than the Nautilus T616. So it’s worth checking the price on Amazon before you buy.

Nautilus T614

T614 Nautilus Treadmill Review

Review rating: 4 star review rating
Despite being their current entry level treadmill, the Nautilus T614 offers some impressive features for the price.

Most of the 22 workout programs are preset profiles, which can be used to help boost your endurance, lose weight, and improve your overall fitness level.

By selecting one of the user profiles before you start your workout, you’re even able to upload your performance data to an online profile via a USB drive. Simply plug the USB into the console, download your workout data, then connect to your computer and start building a history of how your fitness is improving.

The warranty, weight capacity, incline range, and belt speed are all identical to the top-of-the-line T616. But to make the T614 a more affordable option has meant sacrificing some of the motor power (2.75 CHP vs. 3.0 CHP), 4 of the workout programs, and 2 of the user profiles.

The running area on the Nautilus T614 treadmill is also 5-inches shorter than that of the T616, so how do you decide which is best for your budget and fitness goals?

  • Workout programs: 22
  • Heart rate monitoring:
  • Workout tracking: Nautilus Connect™
  • Running area: 20″W x 55″L
  • Incline settings: 12%
  • Workout feedbacks: 13
  • User profiles: 2
  • Weight capacity: 300 lbs
  • Top belt speed: 12 mph

In our T614 review we take a closer look at the design features, console functions, entertainment options, workout programs, and more, to help you decide if you should choose the T614 over the T616.

Nautilus T616

Nautilus T616 Treadmill Review

Review rating: 4.5 star review rating
As their current top-of-the-line treadmill, the Nautilus T616 has an impressive collection of features for under $1000, and is a clear upgrade over the T614.

Not only can you enjoy a wider choice of workout programs, longer running area, and more user profiles, but you can also benefit from a Dual Track multi LCD display and advanced ‘Pacer’ feature.

Pacer lets you race against a virtual opponent, with a series of User Indicator Lights at the top of the console highlighting your progress. Add to this the goal-based preset programs, heart rate monitoring, and powerful 3.0 CHP motor, and you have everything you need to support challenging cardio workouts at home.

Inspired by the Nautilus Fitness Club Line, the larger running area also helps support your stride with an advanced cushioning system that reduces the impact on your knees and ankles.

But how does the Nautilus T616 compare to other well-known treadmills from companies like Sole Fitness, Schwinn, and Precor?

  • Workout programs: 26
  • Heart rate monitoring:
  • Workout tracking: Nautilus Connect™
  • Running area: 20″W x 60″L
  • Incline settings: 12%
  • Workout feedbacks: 13
  • User profiles: 4
  • Weight capacity: 300 lbs
  • Top belt speed: 12 mph

This Nautilus treadmill guide is designed to provide a quick summary of the best features from each machine, so that you can make quick comparisons. But if you want to find out more about the workout programs, heart rate monitoring, entertainment features and data sync to MyFitnessPal, it’s worth taking a look at the full T616 review.
