NordicTrack C 1630 PRO Treadmill Review

Overall, the NordicTrack C 1630 PRO Treadmill is an economy level, mid-priced treadmill suited for running.  However, surprisingly it does possess a feature we would normally only expect to find on higher-end models.

Before going through and explaining these features we first want to mention this review is over the “NEW 2016” version of the model. So we need to point out this version comes iFIT enabled. This application can’t be summed up in a couple simple sentences so we will let the following video show you what its about.

Please Note: The treadmill seen in the video demo is not the C 1630 model which we are reviewing here but the iFit application works the same on all models.

The Best added feature

At the top of this review we mentioned this treadmill possesses a feature normally only found on much more expensive models. What is it? The deck not only has the ability to “incline” but also “declines“, commercial models at gyms usually do not even have this ability.

For weight loss and endurance, we recommend turning up the intensity and working out at an incline. However, working out at a decline provides a different set of benefits.

If you can picture in your mind when you have walked down a hill in your life. What muscles are you using? When walking downhill you are using the muscle that you would use to “stop” or “slow down” when running, walking or jogging. Compared to the muscles we use to move use forward, the muscles we use to stop receive far less stimulation in our daily lives.

In fact, because these muscles are less trained and conditioned, injuries or muscle strains commonly occur when people are in the process of stopping!

Summing up our long winded point, the advantages of being able to workout at an decline include: injury prevention, rehabilitation and also the ability to tone muscles which usually receive little attention.

The most important features

What is the #1 most important feature of any treadmill? This is also probably the last thing most people pay attention to when buying a treadmill.



We don’t recommend buying any treadmill with an inferior warranty. A cheap $400 treadmill, OK you aren’t going to get the best warranty but when paying $1000 plus, you should expect a guarantee. How does the  NordicTrack C 1630 PRO Treadmill grade in the area of warranty?

It provides a lifetime guarantee on both the motor and frame, 5-years on parts and 2-years on labor. The most important part is the lifetime warranty on the motor and frame. Overall, we grade this warranty as an A+.


…You can run

Probably the most common question we are asked comes from people wanting to buy a home treadmill to run on. They are unsure what they need.

Besides the warranty, there are four areas to examine in order to determine if a treadmill is suitable for running. These are: Motor, Tread belt length, frame construction and cushion system.

  • The first thing we look at is how much horsepower the motor has. Our lower limit on horsepower rating for running is 2.5 HP. The second thing we look at is the tread belt length, here our lower limit is 55-inches in length.
  • Since the NordicTrack C 1630 PRO Treadmill has a 3.25 HP motor and also a tread belt 60-inches in length these are suitable specifications for running. Not as important but you should also look at the cushion system and the frame. 

The music in the following video might be a little annoying but overall the does a good job reviewing the pro and cons of this model.


…about the cushion system

This machine is part of the NordicTrack C series. All models in the series do possess a cushion system. The lower quality or less expensive models include the patented “FlexSelect” system. This model includes the upgraded “QuadFlex” system.

The system includes 4 sets (8) spring enclosed dampers located throughout the length of the running deck. We didn’t calculate this but the specifications in the user manual say the system reduces impact by 30 percent. The very best systems found on higher-end treadmills their impact reduction is probably closer to 40 percent. Overall this is a decent system for the money.


…the frame

Not to go into too much detail but the best frames are manufactured from welded steel. Yes this model has this type of frame. The weight capacity of the treadmill is 300 pounds. The frame is under warranty with a lifetime guarantee. All good.


…How fast will it go? 

The motor is what spins the belt, as mentioned earlier the motor is 3.25 horsepower. But we also need to make it clear this is a “continuous duty horsepower motor” (CHP) this is the most durable and efficient type of motor and no matter what model you buy you will want to make sure this type of motor is used.

How fast can you run it? The maximum speed is 12 MPH which would be (60 minutes/12) a 5 minute mile pace.


…designed workout programs

These will be more important to some people than other but this model comes with 34 workout programs designed by certified trainers. The programs are designed to focus on different areas, such as: weight loss, cardiovascular health, muscle toning, endurance and incline training.

The treadmills speed and incline settings automatically adjust as you move through the workouts. Some people may not need these but they are useful, especially, if you are a “fitness beginner” needing direction to help reach your goals.


….Folding Treadmill

For those people who do not have the space to dedicate to a treadmill. While this is not what you would call a “compact model” the overall dimensions are 81.8 x 35 x 57.4 – inches (L x W x H) this is a decent sized footprint. However, when not in use, the deck folds up into a horizontal position which saves a lot of floor space.

If you are a runner who is short on room space. You may have searched for a compact treadmill? This is a whole different category of treadmills. The problem with running on a compact treadmill, for the average person the tread belt length will probably be too short to allow the average person to run comfortably. For runners short on space we would recommend looking into models with longer tracks that are able to fold up when not in use.

…Incline and decline

In the introduction at the to of the page of this review we explained this model has the added feature of a 3% decline which almost no models in this price range include. But what about incline?

Yes, the model also includes the ability to incline at the touch of a button located on the center console. There are 15 different levels of incline. This is a great way to increase the intensity of your workouts no matter what your goals are. Running or walking at an increase grade is a great way to increase the number of calories burned in your workouts.

NordicTrack C 1630 PRO Treadmill – Conclusion

When writing this review in 2016 this model was priced over $1000 but under $1500. On the NordicTrack website at the time of writing this it was priced at $1399. We do not control the prices. It could increase or it could decrease.

With that said, at the current listed price this is one of the models you will want to consider. It is built to handle the impact of running and has a lifetime guarantee on both the motor and frame. Also, if having the ability to exercise at a decline interests you this is one of the only models at its current price range that provides this ability.
