With the best treadmills, you can run or walk at home — no matter the weather or current social distancing regulations. The best treadmills can provide a heart-pumping cardio workout even if the local gym remains closed. That’s why it’s an essential part of the best home gym equipment. 

While running indoors doesn’t have the same feeling of pounding the pavement or trail, many people use home treadmills for their daily morning jog or even marathon training. And pandemic or no, weather conditions have always affected outdoor running and walking regimens. Getting one of the best treadmills ensures you never have to miss a workout. 

There’s a wide range of treadmill options available that meet different, specific needs. You may be looking for a high-end treadmill or a more affordable budget model. You may require a folding treadmill to fit a smaller space. You might want one to mimic certain outdoor conditions. There truly is a treadmill for everyone.

What are the best treadmills?

Our list of the best treadmills is led by one of the most best-known brands in home gym equipment. Like other machines made by NordicTrack, the Commercial 1750 is sturdy, durable and reliable. It comes with a ton of great features, including a large touchscreen to stream iFit workouts (a one-year membership is included with purchase; monthly subscription is required after). The combination of quality, convenience and functionality makes it our top choice.

The Peloton Tread also ranks high among the best treadmills. Like its indoor cycling counterpart, the Tread is beautifully designed. Plus, Peloton offers the exclusive live classes and community features that have made it so popular in recent years. Of course, it’s more expensive than other treadmills on this list. There's a new Peloton Tread model coming out in March, which boasts a 23.8” HD touchscreen.

For those who can’t splurge on a treadmill, the Horizon T101 and XTerra Fitness TR150 are both great budget options that will give users a thorough cardio workout without lightening their wallets too much.

If you’re a road runner or hill climber, the Woodway 4front and NordicTrack X22i are the best treadmills that mimic those conditions. The Woodway machines are expensive but sport cutting-edge technology that feels like you’re pounding pavement. And the X22i has an incline range that cannot be beat — but be sure to hold on to the arm handles.

And save energy while producing more of your own with the Assault Fitness AirRunner, which has a non-motorized belt. You set the speed, so your workout level is entirely up to you.

The premier brand for indoor cycling also makes a high-end treadmill with the big, 32-inch high-res touchscreen that has made Peloton so popular. Of course, it’s not just the screen itself, but the live studio classes it plays. Peloton class teachers have become celebrities in their own right. 

The Peloton Tread is expensive, just like its spin sibling: The new model (due in March 2021) starts at $2,495, while the Tread Plus model starts at $4,295. But if you can afford to splurge, you may fall in love at first run. Runners World lauds the “stunning, angled frame with thoughtful design and a minimalist appearance. It’s a work of art. Thankfully, it runs just as great as it looks.” The Verge notes, “Where Peloton differs is it’s actually entertaining to watch the instructors run with you.”

Toggle between dynamic mode, which feels more like a non-motorized treadmill, and the resistance mode, which is great for HIIT activity.

Trail Runner magazine’s review said, “The max 40-percent incline is burrrrly and not only challenges your quads but your balance” and advised use of the arm handles.

7. XTerra Fitness TR150

The best folding treadmill

Surface size: 16x50 inches | Max speed: 10 | Max incline: 2% | Max decline: N/A | Motor: 2.25 HP | Touchscreen: No | Workout programs: 12 | On-demand/live workouts: No

The inexpensive XTerra Fitness TR150 is best suited for walkers or for light joggers since it has a shorter belt and a lower max speed than other treadmills on our list. The design makes it easy to fold and store away, which makes it perfect for anyone with a small space. The simple LCD console tracks calories, time and pulse, while preset keys allow for quick changes in speed. 

While not a high-end treadmill, the TR150 is a great value, as Amazon reviewers note. “Both my wife and I use the treadmill daily and love it!! It is built solid, and the programs provide us with a different workout each time,” one wrote. Another lauded the small footprint of the machine: “It's not huge, so if you are looking for a space saver-this is it.”

How to choose the best treadmill for you

When choosing the best treadmill for your needs, there are a number of factors to consider. Start with the type of workout you want — hard running, light jogging, walking, etc. If you’re marathon training, you may want better shock absorption and a longer surface length while walkers may find longer arms useful. 

Also think about which treadmill features are most important to you, such as: horsepower; speed; and incline and decline; footprint and portability; and touchscreens. If you want a demanding run as if you’re on hilly terrain, then higher horsepower and higher incline settings are necessary. If you’re a city dweller with a small apartment, a folding treadmill is a must. Another important feature is the content that the treadmill offers, like pre-programmed exercises or live and on-demand studio classes. 

The more features you want, the more expensive the treadmill. Everyone has a different price point, so you may have to trade off some bells and whistles if you’re on a budget.
