Are you looking to get fit without leaving the home or office? Then a treadmill could be the answer! Running on a treadmill has benefits over running outdoors as you can run regardless of what the weather's like. A treadmill can also be gentler on your joints as it provides a level surface and can cushion your footsteps.
There are many treadmill options, and each one is different. That's why we've crafted a buying guide reviewed by a personal trainer to summarize the information you need as well as a list of our 10 favorite treadmills to buy online. We chose the T 8.5 S by NordicTrack as our top favorite because it runs smoothly and has a wide variety of workouts.

A treadmill is a long-term investment, so it's better to take some time to consider your purchase. Since they can be quite complicated and have different functions, we suggest you carefully check all the features that come with the machine before buying.
People buy treadmills for either walking or running, or both! In order to make your workout go smoothly, there are several things you need to consider.
The belt size and speed are two main concerns if your plan is to run on your treadmill. The length of the belt should be around 48 inches for a person under six feet tall. But if you’re six-foot or taller, you might want to consider a minimum of 52 inches of belt length.
For the speed, we suggest choosing one that has a top speed of 10 miles per hour if you're looking to run. However, if you’re at an advanced level or want to do HIIT on a treadmill, we suggest you go for one that has a maximum speed of 12 miles per hour.
I would recommend a 22-inch wide belt for those who prefer to run on a treadmill. This gives you enough space in case of a possible error. Treadmills are measured in miles per hour, so the higher the number, the faster the belt goes. If you are a runner, look for a treadmill that offers speeds over 5 miles per hour.
Many choose walking over running because it puts less pressure on joints and knees. To get the most from your treadmill while you walk or run, you can use the incline function. This will help you gain more muscle on the legs, glutes, and thighs. There aren't many treadmills that come with both incline and decline options, but you can find them.
Manual incline treadmills don’t allow you to program your own workouts. However, newer models of manual treadmills usually come with automatic inclines. They usually have a maximum incline from 10 to 20 percent, but a few models can go up to 40 percent.
A decline option is not as popular as incline because many think that it creates pressure on joints just like running down the stairs. Unlike an incline option, the maximum decline is only three percent on average. Even so, the decline is good for those training for cross-country or hilly races and mimics real-world situations more accurately.
I always love a treadmill with a good incline. Depending on how much of an incline, or if you want an incline at all, will determine which specific treadmill you might choose. The ones that I use go up to an incline of 12, which is super challenging for me to walk at that incline for a period of time.
Treadmill motors are usually described in units of continuous-duty horsepower (CHP). The motor usually ranges from 1.5 CHP to 5 CHP. If you plan to walk, we suggest looking for a machine with 1.5 CHP to 2 CHP for average-weight individuals.
If you plan to run, it's better to choose a motor of 2.5 CHP or higher. Plus, if you're an individual of above average weight or height, it's best to look for motors that have a higher CHP than these recommendations. You can use BMI charts to determine whether your weight is above average for your height. For manual treadmills, it's best to consider the maximum weight recommendations.
Manual treadmills that don't require electricity are an additional option. The belt moves as your feet do, but these treadmills do make for a more strenuous workout. While manual models help you save on your power bill, they aren't as sturdy and require manual incline adjustments. Manual treadmills are best for those who plan on walking.
Always measure your room space before buying! Most importantly, make sure that you have as much space as possible behind the machine to prevent the risk of accidents. You should also take into account that a treadmill will raise you up higher, so be careful of low ceilings and nearby ceiling fans.
Folding treadmills are a good option for compact storage when you’re not using them. They're also easier to transport when you’re moving to a new place. In addition, they make cleaning much quicker for you. You will have an easier time cleaning the machine itself, underneath it, and the surrounding areas.
Space is crucial! Make sure you have space to run. Make sure you have space to put the treadmill so that you don't feel trapped. Make sure you have a room that is safe! I always recommend measuring the space you wish to put the treadmill in before purchasing. You want to make sure that it is a functional space with that large piece of equipment.
Everyone wants to focus during a workout in order to get the best results. In the case of running, treadmill cushioning and stability are what you need to look at. Their benefits are not only to increase your running performance but also to prevent the risks of injury.
Every step on the treadmill’s deck creates pressure on your knees and joints. Cushioning helps to support your joints during running and can also stop the belt from moving around with every footstep.
Belt thickness or width is something to look into as well, as it can impact cushioning. The ideal thickness is different depending on whether you're mostly a runner or a walker. Most treadmills for home use have a belt thickness between 0.8 millimeters to 1.1 millimeters. Commercial-grade machines will typically have a belt thickness between 1.8 millimeters and 2.2 millimeters.
Stability is another important thing to check. We suggest that you check a lot of reviews and compare before buying. Customers may comment that the treadmill is a bit shaky or feels unstable during use, and that's a good indicator that you should stay away. Many treadmills require some home assembly, and this can also contribute to how stable a treadmill is.
In addition, an emergency stop button or clip is another important function that most people overlook. These ensure that the machine will automatically stop if you get too close to the back edge of the treadmill. This can reduce the chance of falling from the treadmill.
Safety features....yes! Who is guilty of skimming over safety features in the past? Well, make sure you don't skim over these important features when choosing a treadmill. Nowadays, most treadmills are equipped with emergency stop systems that include a panic button or a tether with a clip. I love this feature!
Many home treadmills offer control panels with preloaded workout and training programs for different fitness goals, such as weight loss or building endurance. These programs automatically adjust the treadmill's incline and speed.
Some have predetermined workout times, such as 45 minutes. Others let you set the time and enter your current age and weight. The programs use this information to make adjustments depending on your personal heart rate range for fat burning and cardio.
There should also be an option to operate motorized treadmills in manual mode, which lets you have complete control over the incline and the belt's speed. Separate controls on motorized treadmills should let you manually adjust the belt's speed and incline during your workout.
Another feature you might want to consider is a treadmill that comes with a desk that gives you the chance to read books or use a tablet during your workout. Some treadmills also have docks for cell phones, spaces for water bottles, and cooling fans with adjustable speeds.
No matter how many options a treadmill has, you should make sure it's easy to use! A treadmill that has a lot of options may not be worth it if you can’t figure out how to use all of its features. Check reviews to see if buyers thought it was easy to use, or at least make sure it comes with a good user manual or playlist of YouTube videos.
Several treadmill manufacturers integrate technology, such as iFit and the Peleton app, that allows you to connect to Google Maps, interact with coaches around the world, and race with other users to increase your motivation to work out. These features often require an additional subscription, so make sure to check this before you buy.
Some treadmills come with heart rate monitors that connect to your chest while you're working out. Connected monitors provide better accuracy than handgrip monitors. You will also benefit from continuous monitoring so you can gain insights into your heart rate variability. Another advantage is the ability to measure how long you were in fat-burning or cardio modes.
Of course, built-in technology features do not stop with subscription workout apps and heart rate monitors. There are also LCD televisions and speakers for your music. Connect your smartphone and listen to your favorite workout playlists from an app like Spotify or Amazon Music.
As a treadmill is a long-term investment, a warranty is another important thing that you should carefully check. Shorter warranties usually mean a lower quality treadmill because it can possibly break sooner. A 10-year frame warranty and two-year general warranty are what we recommend.
However, buying a treadmill online can be more complicated because you don’t get to ask questions directly to salespeople. If you’re unsure about the warranty, it’s better to call the seller and ask them for confirmation. You can also check reviews to see if previous buyers have had any issues resolving problems.
Other important things to consider are a treadmill's weight and assembly. Manual treadmills weigh about 60 pounds. However, motorized treadmills weigh 200 pounds or more. Figure out whether you will need help moving the treadmill to your designated workout space. Also, ask whether you can include assembly services. The process can take hours and be confusing if you try to do it yourself.
Make sure your treadmill has a warranty! Something you don't ever want to deal with is the belt acting up or something breaking on it not even a year in, and then simply neglecting the machine altogether. Invest in a good machine because you deserve it. Most treadmills last 10 years, but their warranty is usually 2.

In addition to reviewing and commenting on our buying guide, Gentry has also taken the time to answer a commonly asked question about treadmills.
"It all depends on preference," Gentry explains. "An elliptical is better on the joints (if you are using a treadmill to run). But both are great machines that achieve similar outcomes."
