Curved Treadmill Benefits

Now that we’ve had a good look at the 7 best curved treadmills for sale, we should probably discuss what the hype is all about.

Are they really all they’re cracked up to be?

Well, the answer depends on what you’re looking for.

From a fitness perspective, curved treadmills bring with them a great deal of benefits.

Some of the health benefits will be the same as traditional, motorized treadmills like improved cardiovascular health, weight loss, increased muscle tone, convenience, and more.

According to various sources and research, however, it’s been found that you use more energy when using a curved, non-motorized treadmill.

This means you have to work harder, will burn more calories, and get in a better workout in less time when compared to traditional running or running on a traditional motorized treadmill. 

Curved Treadmill vs Flat 

Curved Treadmills For Sale

As mentioned above, both curved and flat treadmills bring many health benefits to your life if you are using them regularly.

However, just because they share several benefits and they are both used for running indoors doesn’t mean that they are the same by any stretch of the imagination.

They have some foundational differences.

First, as the names suggest, curved treadmills are, well, curved.

They are also non-motorized and work off of your body weight and the friction you create when moving your feet.

Instead of simply pushing a number on a traditional motorized treadmill and setting the speed you want to run, you work your way to that speed in a more natural way with the curved treadmill. 

Another difference between the two treadmills is their use of energy and power.

Most non-motorized treadmills are relatively low tech, with some not even requiring an outlet to be used.

Most have a simplistic battery-operated display screen showing calories burned, distance, and other basics, but that’s about it.

In some of the really high end versions, you will find comparable tablets offering more programs, however, this is in the minority.

With traditional treadmills, you will more than likely find more bells and whistles, customized and pre-set programs, options, incline, and more.

Therefore, traditional motorized or “flat” treadmills will require an outlet and more use of power. 

Are curved treadmills better?

Now that we can see the differences between a curved and flat treadmill, the question arises… Which is better? In all honesty, the answer genuinely depends. 

If you are looking at it from a health perspective, curved treadmills are better in the sense that they burn more calories and make you work harder naturally.

Not only are you burning up to 30% more calories with a curved treadmill because of its design, they have also found that users have 16% higher average heart rates and use over 30% more oxygen than with non-motorized treadmills.

However, flat treadmills also have features such as incline and varying speeds that can allow more versatility into your tread workouts like HIIT and more. 

It comes down to a couple of factors when determining which type of treadmill is best for you.

You’ve got to consider your physical space and your availability of power outlets.

You’ve got to think about the workouts you want to do from your home, and you’ve also got to consider your budget. 

Curved Treadmill Price

Curved Treadmills For Sale

Speaking of budget, what should your budget be if you want to invest in a curved treadmill?

We’ve shared treadmill buying guides before for motorized treadmills in varying price ranges under $1,000 and under $2,000

When you’re in the market for a curved treadmill, you’re probably going to need to budget a little more.

While you might find a curved treadmill around the $1,500 mark, most of the best curved treadmills for sale on the market are going to be at or above $3,500.

Some, like the SprintBok, can be even more.

Why Are Curved Treadmills so Expensive?

You may experience a little sticker shock after learning how much curved treadmills can cost.

However, there’s obviously a reason that curved treadmills can cost considerably more than flat treadmills, despite having less technology.

There are several reasons curved treadmills are so expensive, so let’s look at the most important reasons.

  • Materials

One of the biggest reasons that curved, non-motorized treadmills are more expensive is because of the materials.

If you’ll notice from our list of the 7 best curved treadmills, most are incredibly heavy, weighing in at 250 pounds and more.

This means that they make them of hearty, high quality, and sturdy material, which also means that they can typically handle heavier weight capacities as well.

Besides the materials being expensive because they are heavy and high quality, they are also more custom.

With the curved nature of the treadmill, the materials will need to be bent or strategically designed for this unique style.

This means it will take more time, effort, and engineering to get the technology just right. 

  • More Craftsmanship

As I mentioned above, the curved nature of the non-motorized treadmills means they require a much more detailed design process than a traditional flat treadmill.

In order for the treadmill to be durable, it not only needs to be made of high quality and sturdy materials, it also needs a lot of attention, engineering, and planning to be sure that it both looks good and rides good for a long time.

This level of craftsmanship needed for these types of treadmills will definitely translate to costing more money! 

  • Shock Absorbing Technology

While there may not be as much “technology” as traditional treadmills in terms of screens and programs, they infuse a lot of the technology in the design of the curved treadmill itself.

To heed excellent results in a quality treadmill, it has to absorb more of your steps as you are walking or running to prevent injuries, discomfort, and overall feel while using it.

A great deal of research, effort, and trial goes into designing the curved tread to work with your feet and the pressure point created while running.  

How To Use a Curved Treadmill

By now, you should have a pretty good grasp of the ins and outs of curved treadmills, how they don’t require any electricity or power other than man-made power from moving your body.

But you may still wonder how to use one. 

Luckily enough, they’re so simplistic that they are really easy to use.

Because they don’t have too many technological features or complicated mechanisms, you simply run like you would outside on the pavement. 

At first, the curve of the treadmill will take some getting used to.

It will feel different from running outside, but the main idea is the same.

Simply start by walking and slowly increasing your pace to your desired running speed. 

As you begin your journey on a curved treadmill, it’s always important to take things slow.

Allow your body to adjust before diving into sprint training, and you’ll be good to go!
