Serenelife is a relatively new company that has made waves in the low-cost cardio market. Their entry-level treadmill is an excellent option for those on a budget and with limited space.

Assembly is quick and easy, taking only 10 minutes, and the machine is fuss-free. Despite its compact size, the treadmill doesn’t lack features—it boasts a large backlit LCD screen and 16 built-in workout programs that can be programmed according to your needs.

The only downside to this compact design is that it has no storage space for shoes or other accessories; however, if you don’t plan on using any accessories, this should be fine!

There’s also an electronic belt tensioner built into each side rail, ensuring consistent tension throughout usage, so it will be smooth no matter what happens during your run.

After testing this SereneLife Folding Treadmill at a gym, I was impressed with its soft drop cushioning deck, which is a big plus for anyone using treadmills at gyms.

The motor was quiet enough for me to talk to someone on call without any disturbance, and the treadmill itself is very lightweight, making it easy to move around when needed.

However, I did find some drawbacks, such as the running belt being too short for my 6’3″ friend. I felt sweaty, and there was no cooling fan for me to relax a bit.

Also, I asked the gym owner about its assembly, and he told me it could be challenging for any average athlete.

After testing the XTERRA Fitness TR150, I was impressed by its built quality and reliability for its price range. It has not malfunctioned, and I have used it for two months.

XTERRA Fitness TR150 Features

However, it is thin and lacks cushioning—so every step you take feels loud. The treadmill might not be a good choice for your living room if quiet floors are essential, but it’s great for someone who does fast-paced walking or needs a machine that can handle more weight than others (250 pounds).

As it is better for heavyweight people, you must remember it has a smaller running space area, so if you are under 6 feet, this treadmill is for you.

The belt is made of cheap and thin material, so stepping on it feels like walking heavily through the mud.

Overall, I would give this machine a 4-star.


  • Low cost.
  • Three inline positions.
  • Integrated heart-rate monitor.
  • Easy assembly.
  • Built with high-quality.


  • It might be challenging to assemble.

Testing Goplus 2 in 1

After testing this treadmill, I was impressed that this folding treadmill came fully assembled, and you don’t have to improve at putting things together.

However, I was disappointed that the remote control had no battery.

Before purchasing this treadmill, remember that it has no decline/incline feature and even a tiny running surface area. Make sure to check your height accordingly.

Sperax Treadmill At Home

Although the treadmill is designed for low-impact exercise and can help you burn calories while working out, it’s important to note that this model may not withstand running or jogging.

I wouldn’t say I liked the feature that the speed was being shown in Kph and not Mph, which is in most treadmills.

The less running surface area size might be a big problem for taller users. If you are taller, look for other options on our website. I recommend the Sperax Treadmill to anyone who wants to stay active while working from home.


  • Lightweight.
  • Quiet motor.
  • Doesn’t require assembly.


  • Less running surface area size.
  • Speed is measured in Kph and not Mph.

Benefits of Treadmill Under $400.

Treadmills are a prominent choice for home exercise equipment, but their prices vary greatly.

These $400 treadmills may lack some of the best features found on other models, but that doesn’t mean they can’t give you a great workout. After I tested all of these treadmills mentioned above, I was impressed with the quality they had.

The best treadmills under $400 are built to provide a great workout for the price. Many of them come with incline features if you properly search out!

The benefits of a treadmill under $400 include maintaining your heart health, they are lightweight and they are also moveable for those who don’t want to face difficulties while moving the treadmill.

1. Heart Health

Using a treadmill is a great way to strengthen your heart. By reducing body weight, raising energy levels, and lowering blood pressure, cholesterol, blood sugar, and blood sugar levels—all of which can help fend off heart disease or stroke in the future!

The American Heart Association recommends individuals exercise for at least 150 minutes a week of moderate-intensity aerobic activity, 75 minutes a week of strenuous aerobic activity, or a combination of the two, preferably spread out equally throughout the week.

Due to the fact that they demand you to utilize more muscles than other forms of exercise like jogging or cycling.  Treadmills have also been proven to reduce physical stress on the body.

This indicates that compared to other forms of exercise, using a treadmill requires burning fewer calories per minute.

2. Weight loss:

Nothing can help you lose weight as effectively as a treadmill. Depending on how hard you work out, a treadmill adjusted to the right speed and slope can burn up to 350–500 calories per hour.

Weight Loss

This is a lot more than conventional exercise equipment is capable of. Interval training is another activity you can perform on the treadmill to burn more calories faster. There are numerous approaches to weight loss.

If you follow a healthy diet and exercise every day, you can lose weight quickly. Treadmills are the best alternative available for exercising.

The American Heart Association claims that maintaining a 2 mph pace while using a treadmill with a 3.5% incline is just as safe.

3. Lightweight and Moveable

The weight of a treadmill is also a really important factor as it might decide the assembly and transportation of your treadmill. If it is heavy you might need to face some difficulties in its setup process.

A lightweight and moveable treadmill would be a better option for those who don’t want to face some difficulties of moving the treadmill or folding it to put it under the desk.

Thus, if you want a treadmill that you can easily move and put under your desk, consider a treadmill that is less than 70 pounds. This is a better option for those who travel a lot!

4. More Budget for more Equipment:

You can also have money left over to spend on other equipment if you buy a treadmill for less than $400. Spending $400 on a treadmill rather than $2000 will leave you with more cash to spend on other pieces of equipment.

Get a stationary bike and an elliptical trainer as well, don’t forget. Weights, resistance bands, and/or a fitness ball are further options.

In the end, you will want to pick a treadmill that is worthwhile. Also, it should be strong, simple to use, and equipped with features that will help you reach your exercise objectives.

You can accomplish more and burn more calories with the aid of this equipment beginning your path to fitness.



What to look for in a treadmill under 400$?

Before buying any treadmill, whatever the cost is you should always research before buying it. Obviously, you would use a treadmill with the best features under your budget.

So, whenever you are buying a treadmill for under $400, consider the following features:

1. Incline Feature

It’s vital to keep in mind that many inexpensive treadmills lack an incline option, and even more costly models may not have this convenience if you’re looking for a treadmill that will help you get in shape but won’t break the bank.

incline on the treadmill

It is better to get a treadmill with at least one incline setting. The majority of models have several levels, however, it could be difficult to find a power-adjustable inclination that fits inside your price range.

By targeting your quads, hamstrings, glutes, and even the smallest muscles in your feet, incline workouts can help you tone your muscles more efficiently.

Incline features can stimulate walking or jogging uphill or even down the hill. This will help you in focusing on any body part you want.

2. Price

One of the key factors to think about when buying a treadmill is your budget. Even though the features of the most recent model could fascinate you, it’s important to take your frequency of use into account.

If you’re a heavy user, it’s advisable to spend more money on a treadmill that is higher quality, more sturdy and will last longer. Consider purchasing an entry-level model if you’re searching for something straightforward.

Spending more money, though, can be preferable if you’re seeking gear that will only be used seldom or if you run moderately.

3. Motor

Also, consider the power of the motor. While commercial-grade equipment can typically boast powerful motors, budget machines may not measure up in this regard.


The power of a treadmill motor (measured in horsepower) can affect the performance and longevity of your machine.

Some motors used in lower-priced treadmills have less than 2.25 horsepower, which may need to be increased for running on hills or inclines.

So, just try to have a treadmill with a horsepower of more than 2 in such a range of budget.

4. Weight Limit

The weight limit on your Treadmill is another essential factor to consider. Commercial-grade treadmills typically have a higher weight limit than budget machines (which may top at around 350 pounds).

However, for a budget under $400, the weight limit of 250-300 is acceptable, and you will mostly find them in such ranges.

This is important because it can affect the longevity and durability of your machine—especially if you’re larger or heavier than average.

5. Folding mechanism

Within the price range of under $400, most treadmills come with the convenience of foldability. This feature can be beneficial if you have little space for a treadmill; Folding makes it more compact and easier to store.

When searching for a folding treadmill, look for systems that make unfolding and refolding machines as simple as possible. Some inexpensive models can be frustrating to fold/unfold, so watch for easy-to-use versions like a soft drop.

If space is limited, a fold-flat treadmill can be an ideal option. These machines can be folded almost flat, stored under beds, or propped against walls.

6. Running Deck Size

Running decks are the surface where your feet touch when running. They come in a variety of sizes, but most treadmills.

Under $400, you can easily find a treadmill with a running deck size of 36″- 50″. This is the ideal size for most people, but finding a model that fits your height and weight can be complex.

If you’re tall or overweight, look for treadmills with larger running decks. Likewise, consider a treadmill with a smaller deck if you’re short or lightweight.

7. Speed

On a treadmill, the speed is measured in miles per hour (mph). Although most treadmills have a speed range of 0–10 mph, certain models have a 0–12 mph option.

Consider choosing one with a higher peak speed if you want to shed pounds and become in shape.

It’s generally not necessary if your primary objective is to maintain your current weight or increase muscular tone, though. Along with different speeds

8. Warranty

When investing in a treadmill, it’s essential to consider the warranty that comes with it. A good warranty will cover you if something goes wrong with your Treadmill, such as motor failure or damage during shipping.

However, considering the budget, the warranty might be one or two years, one frame, and a few months on other parts.

The best overall home-use Treadmill would be the GoPlus 2-in-1 Treadmill. This Treadmill has some of the best home-use features and will last you for years. The compact size can help you move this treadmill anywhere in your home without injuries.

Small apartments are the ideal place for inexpensive treadmills. They can be transported more rapidly than more sturdy versions of these equipment since they are lighter-duty. Also, they are less expensive, which is a benefit. If you only want to use a treadmill sometimes, you don't need to invest hundreds of dollars on one.

Is a treadmill better than free walking?

A treadmill can help you lose weight and get in shape. It gives you a more complete experience in addition to a more effective workout. In a study that was published in the journal Medicine & Science in Sport & Exercise, treadmill walkers burnt about 304 calories in an hour as opposed to merely 258 calories from free walking.
