If you were on the hunt for the best treadmill under $400, we have your back with everything you need to know. 

Generally, treadmills are considered an expensive piece of gym equipment. However, there are categories for any piece of equipment, including treadmills. There are budget options that don’t cost a lot but are low on features, mid-range options that offer a bit more functionality than budget options, and at the very top are premium treadmills in the thousands of dollars price range.

Best treadmill under $400 overall

No products found.

250-pound weight limitNo Bluetooth
XTRASoft cushioned deck technologyRunning deck might not be spacious enough for taller people
10 MPH top speed
12 preset programs
Easy foldability

If you’re looking for the best treadmill under $400, check out the Xterra Fitness TR150.

Let’s kick things off with some general specifications. This treadmill weighs 97 pounds/43 kg, has a maximum weight capacity of 250 pounds/113 kg, and features a top speed of 10 MPH/16 KPH. What this means is that it should be durable enough to handle everyday usage and cater to individuals of varying sizes. 

On top of that, the speed range (0.5 – 10 MPH) should allow you to find and work at your own pace, whether it’s walking, jogging, or running. Furthermore, it should be light enough to be moved around the house or apartment, but asking your partner or any friend for help is still advised to avoid injury. 

The TR150 has a size of 63.4” L x 28.75” W x 51.4” H, which is reasonable. However, folding it turns its dimensions into 28.5” L x 28.85” W x 61” H. The height increases because the running deck folds vertically, but that saves the most space and should enable you to store it against a wall or even in a closet if it’s big enough. 

Folding and unfolding it is also easy, as you simply need to pull on the knob on the side, fold it up, and release the knob to lock it in place. While auto-folding features would be nice, we need to keep in mind the price range this treadmill falls in. On top of that, it has built-in wheels that should make moving it around easy, and you won’t have to lift it. 

It has a 50” L x 16” W running deck, which should be enough for most runners, but the great part about it is the XTRASoft cushioned deck technology. What this means is that while you’re running, it should absorb a good amount of the force and take it away from your joints, leading to better joint health and a comfortable workout experience. 

This treadmill features 12 preset programs that should offer an efficient way to work out and try something new. These programs can be sorted through the center console, which also has direct access buttons to set the speed to the desired level. 

Overall, this treadmill has a lifetime frame warranty, pulse sensors, a 2.25 HP motor with quiet operation, and a handful of other features. All these combined give it the top spot on our list, and we see it reigning for a long time.

Best folding treadmill under $400 overall

No products found.

9 MPH top speed 220 pounds weight limit might be low for some
Soft drop system for easy foldability
Nine built-in programs
Shock-absorbing running deck

If you’re looking for a treadmill that has space-saving capabilities, we recommend you check out the Sunny Health & Fitness SF-T4400. 

First off, this treadmill has a maximum weight limit of 220 pounds/ 99 kg and a top speed of 9 MPH/ 14 KPH. Its weight limit is lower than what we’ve seen on other treadmills, but it should be able to cater to most people easily. Furthermore, 9 MPH should be enough for beginners and advanced runners alike. 

It also has a maximum manual incline of 4.3°. While this isn’t a lot, it should offer something different from the usual training programs and result in a more dynamic workout. 

On top of that, its digital monitor shows information such as speed, time, distance, calories, and pulse. This should provide insight into your performance and how you can efficiently adjust it for the best results. It also has quick access buttons, which you can use to increase or decrease the speed directly. 

This treadmill’s running deck is 49” in length and 15.5” in width. What this means is that it should provide enough space for average-sized people. However, if you’re taller than average or are a bit on the heavier side, you might feel that the running space isn’t a lot. However, it features a shock-absorbing deck that should remove some impact from your joints, resulting in a pleasant running experience. 

It also has a soft drop system, which means that you can fold the running deck vertically. To unfold it, simply nudge the lever, and it’ll float back down. This should save space when you’re not using the treadmill and make transportation easier combined with the built-in wheels.

As for accessibility features, it has a bottle holder, device holder, pulse sensors on the handrails, and nine built-in programs that should add a bit of versatility to the mix. 

Overall, looking at its price bracket and the features and functionalities this treadmill offers, we think this is the best folding treadmill you can buy for under $400.

Best treadmill under $400 for seniors

No products found.

Speed increment of 0.1 MPH lets you find the perfect paceNot for running
300-pound maximum weight limit
Large buttons 
Detachable side rails

If you’re looking for a treadmill under $400 for seniors, the Redliro JK16080L might be your option. 

For starters, this treadmill weighs around 68.3 lbs/30.9 kg, has a maximum speed of 5.5 MPH/8.8 KPH, and can support up to 300 lbs/136 kg, the highest on this list. What this means is that it should be able to cater to a wide array of people and be light enough to be moved around. However, for older adults, it is recommended to employ the help of others. The 0.5 – 5.5 MPH speed range should be enough for walking or slightly faster jogging, but running might be difficult.

It has a five-layer running belt with a shock absorption design. This means it should reduce the impact on the joints and muscles and lead to a comfortable walking or jogging experience. On top of that, it has extra long handrails that can be removed but offer extended support for aging adults while they workout.

This treadmill also has compact dimensions, but more than that, the running deck can be folded vertically and transported to different rooms via the built-in wheels. 

Lastly, the center console sports a large LCD that shows information like distance, speed, time, and calories. The control buttons to adjust the speed, shuffle through the 12 preset programs, change the mode, and start/stop the treadmill are large with clear writing. This should help older adults better understand how to control the treadmill without unnecessarily fiddling with the controls. 

All in all, its high weight capacity and accessibility features make it one of the best treadmills you can buy for seniors for under $400.

How to pick the best treadmill under $400

Choosing a treadmill under $400 can be challenging, and going for the most prominent name isn’t the best move. There are various factors that you need to consider so that you’re able to invest your money wisely. Here are a couple of those factors: 


The first thing you need to consider is the comfort of the treadmill. This includes aspects such as deck cushioning and deck size. If the treadmill has poor cushioning,  the impact won’t be significantly reduced and will most likely affect your joints. 

On top of that, if the deck size can’t handle your stride length or size, it’ll feel cramped while you’re working, leading to an uncomfortable experience. 

Top speed 

Depending on your fitness level and how much experience you have in running, the treadmill’s top speed might be the factor that makes or breaks it. For example, if you’re used to running at 6 MPH, a treadmill that offers more will be better as it’ll provide room for improvement. However, if the treadmill’s top speed is 3.8 MPH, it’ll just hinder your progress. So, go for an option that offers a good balance between where you are and where you can be regarding your fitness. 


This is an important factor to consider if space is a concern for you. If your living space is small, then it’d be better to opt for a treadmill that has a low footprint or can be easily folded. This will save space when you’re not using it and might make storing it easy, depending on its weight. 

Weight limit 

If the treadmill you’re looking to buy can’t support your weight, there is no point in purchasing it. Going above the recommended weight limit might damage components and void the warranty. So, choose a treadmill that can easily handle your weight and has enough overhead. 

How many years does a treadmill last? 

Generally, a treadmill could last you anywhere from 5 to 15 years. However, that depends on many factors, such as how often you use it, how you use it, and how often it is getting maintenance work done. These factors combined will affect the treadmill’s longevity, and generally, the rule is that the better you treat your equipment, the longer it’ll last.

After considering the features and specifications of the listed treadmills, we concluded that the best treadmill under $400 is the Xterra Fitness TR150. First, it has a maximum weight capacity of 250 pounds, a maximum speed of 10 MPH, three incline levels,  XTRASoft cushioned deck technology, and 12 preset training programs for added versatility.
