The 6 Best Treadmills Worth the Space in Your Home Gym

What to Consider

Dimensions

When you are building a home gym, space is a precious resource, and treadmills can take up a significant amount. Be sure to check the dimensions of any treadmill you're currently shopping. Be sure to add at least 1-2 feet in every direction and three feet or more behind the treadmill (the area you step on to the machine from) for maximum safety.

One thing buyers also tend to overlook is the height. You’ll want at least 15” inches above your own height when standing on the treadmill. So, if you’re 5’10” (70 inches), make sure your ceiling height is enough to accommodate 85 inches, plus the height of the treadmill belt. This is especially important if you’re planning to use your treadmill for running.

Lastly, be sure you are considering the amount of space you are going to need for storage if you aren’t planning for the treadmill to be left out when you aren’t working out. There are some great folding treadmill options, and models that can be moved or positioned easily, that can help you make the most of the space between runs.

Deck Size

Looking for a treadmill suitable for running? Or maybe you just want a reliable machine to walk on while you watch TV. Whatever you’re looking for, you’ll want to ensure the deck size suits your activity preferences (and your height). The industry standard for a walking treadmill deck is 55 inches by 20 inches, and at least 60 inches by 20 inches for running. You may be able to get away with running or walking on shorter decks, but this means altering your stride length, which means you’ll have to think about every step you take.

Stability

This might seem obvious, but double-check that all four corners of the treadmill are firmly in contact with the floor after setup. Many home floors aren’t 100% level (you'd be surprised). You want to make sure that your treadmill is well-planted to minimize the risk of slippage, shifting, or tilting.

Noise

Treadmills can—and often do—make a lot of noise, especially for your downstairs neighbors (if you live in an apartment) or housemates (if you live in a multistory house). If you think this might be an issue, consider a treadmill mat to help minimize the noise. These simple and usually affordable mats can help deaden the sound and vibration on the floor beneath a treadmill. However it won't quiet down the belt itself, and we’ve made a point to suggest models that won’t screech above your gym playlist.

Power Required

Treadmills—especially large and commercial models—can draw significant power. If your home’s electrical setup allows, dedicate one circuit to just your treadmill. This will help ensure that other power-hungry devices potentially on that same circuit don’t blow a fuse.

Speed & Incline

Nobody wants to drop the money for a treadmill that isn’t going to keep up with their workouts. Be sure to decide what kinds of speeds and inclines you are going to require for your training goals. The fact is treadmills will have different capacities when it comes to these features, and while 12 mph might be enough for some, it may not be enough for sprinters. The same goes with inclines. Most brands are transparent about the motor’s horsepower but some don’t disclose on the treadmill’s spec sheet. For reference, you should look for at least a 3.0 CHP motor if you plan to run or sprint regularly.

Warranty

The industry standard for a treadmill frame warranty is 15 years to life. This is the standard for mid- to high-dollar treadmills, but if you’re buying some random machine off of Amazon for $200, don’t expect this type of guarantee. We also recommend immediately registering your machine on the brand’s website after purchasing to make sure you’ll be able to cash in on the warranty if you ever need to do so.

Frequently Asked Questions

Should I Buy a Curved Treadmill?

Maybe. It all depends on your personal fitness level and goals. Curved treadmills are non-motorized. They rely instead on you walking or running, and the belt being pushed backward manually with every foot strike on the sloped surface. While this might not seem as "fancy" or high-tech as a powered treadmill, this design has its benefits.

"Curved treadmills tend to recruit more muscles due to the shape of the belt and the act of propelling against it," says Eric Sung, C.S.C.S., a member of the Men's Health Strength in Diversity initiative and trainer at Performance Lab in New York City. "It also eases the strain of your joints because of the curvature and is often better for users with varied joint pain."

By some reports, exercising on a curved treadmill burns 30% more calories over a traditional powered treadmill.

"One drawback of a curved treadmill is that it is difficult to achieve higher speeds (sprints) with proper technique. This can impact front side mechanics with one's stride through by 'reaching'," explains Sung. Another thing to consider: Because curved treads are motorless, they also don't allow for incline or decline capabilities.

Does Running on a Treadmill Affect Running Mechanics?

Yes, although not critically, according to David Siik, founder of Precision Run by Equinox.

"To create a sense of security, people tend to run far too close to the front of the treadmill," he explains. This can lead to a compressed posture, restricting the range of motion in your arms. Siik recommends maintaining at least one foot of distance between your belly and the treadmill monitor.

Treadmills may require slightly less engagement of our hamstrings compared to outdoor running, though the difference isn't substantial, Siik tells us.

"Another important point we emphasize with our runners and walkers is the importance of avoiding the habit of constantly staring at your phone while using the treadmill." Over time, this posture can strain your neck.

Benefits of Running on a Treadmill

Jonathan Cane, an exercise physiologist, running coach, and founder of City Coach Multisport in New York City, highlights several benefits of running on a treadmill. He mentions that treadmills allow for the simulation of terrain, making them valuable for training when natural hills or elevation changes aren't readily available. This feature is particularly useful for preparing for hilly races.

"Walking up a grade can have comparable cardiovascular benefit to running flat, yet doesn't have the associated orthopedic stress, so it can be a great way to get a workout without all the pounding you might have with running," he explains.

Siik explains that the benefits of running and walking on an incline boil down to the increased energy spend (remaining calories burned) caused by the increased power needed to climb vertically.

"Variation is key to experience the full benefits of incline. Steep inclines have wonderful energy burning benefits but also can destabilize the knees over time if done frequently," he explains. "This is why the treadmill is beautiful for incline training; it allows you to play with such a spectrum of programming."

Treadmills also offer the advantage of being weather-independent, with modern models featuring softer surfaces that are gentler on the body compared to running on hard asphalt or concrete. (Remember: Running outside exposes you to the elements, which can have additional mental and physical benefits, so do it when possible.)
