Best Curved Treadmills for Sale [2021 Buyer’s Guide]

Curved treadmills have garnered a lot of hype over the years. The overall shape allows users to build a better and more efficient running form.

What is a Curved Treadmill?

A curved treadmill is a non-motorized treadmill built at almost a 30% incline. The self-powered treadmill requires users to use more natural force to move. This, in turn, exerts more energy and calories overall. During the downward movement of your run, your foot and weight pull the belt down and back. This allows you to pace your run and burn more fat.

Some people consider curved treadmills to be the best manual treadmill for jogging because it allows the runner to establish a pace and improve running efficiency. A curved treadmill sprint is also going to work and tone the user’s legs a lot more because he or she is providing all the power.  Various training methods also make curved treadmills a popular option for home and commercial gyms.

Benefits of Curved Treadmills

There are a ton of curved treadmill benefits, which help both in weight loss and cardiovascular health improvements.

Running Shoes

Become a More Efficient Runner

These U shaped treadmills require the runner to plant with the balls of his or her feet. Most people land on their heels when running on a regular treadmill which can often lead to unnecessary injury. Additionally, runners can expect to improve posture and stand taller with ever run. Often times, runners add an unnecessary forward lean when running outside. This creates an imbalance in your form which can lead to an inefficient run. Running tall also allows more activation in your core and glutes, helping to build a stronger and more muscular frame.

Burn More Calories and Fat

When you use a manual treadmill for running, it requires more effort with each stride to continue moving. Curved treadmills are said to burn almost 30% more calories than regular treadmills because you have to keep the belt moving. Increasing your pace to a sprint requires significant leg drive on a curved treadmill versus a motor doing all the pull on a regular treadmill. The increase in caloric burn also helps aid in fat loss and improve overall body definition.

Easier Maintenance

Without as many moving parts as regular treadmills, curved treadmills are a lot easier to maintain, especially in big commercial gyms. The lack of electricity also makes curved treadmills a lot more environmentally friendly as well.

Assault Air Runner vs Treadmill

Other than the shape of the machine, the biggest difference between the Assault Air Runner and a traditional treadmill is how it is powered. Most traditional treadmills you’ll find in a gym or in someone’s home are powered by motors, which are measured in horsepower, while the Assault Air Runner is entirely manual.

Not only will this provide a really great workout since the user has to all the work with his or her legs, but it also helps eliminate future mechanical issues. A good quality treadmill will come with a good warranty, but there’s always the potential for parts breaking in the long run. Obviously, the Assault Air Runner isn’t indestructible, but limiting the amount of potential mechanical issues is always a plus.

Curved Treadmills vs. Regular Treadmills

You might not be sure if you want to purchase a curved treadmill or flat treadmill for your home or gym, so it’s important to know the main differences.

Speed Changes

Motorized treadmills have automatic settings to adjust the speed. Most come with a digital control panel for you to easily make the adjustment. Manual treadmills, on the other hand, require the user to exert more energy to increase the speed. Because of this, curved treadmills offer a more unique and efficient workout overall.

Technology Features

Most manual treadmills lack a lot of the cool bells and whistles found on motorized treadmills. In fact, some curved treadmills don’t even have a basic heart rate monitor. While this may be a turnoff for some people, it’s also important to remember this makes maintenance a lot easier as there are fewer moving parts.

Price

If you are looking for a treadmill with a lot of advanced technology, you’re probably going to pay around what you would for a curved treadmill. If you are on a budget or want something more cost-effective, you’re better off going with a lower end motorized treadmill like the NordicTrack T 6.5 S for example.

Weight Loss

Cardio workouts are a great way to lose weight, with high-intensity interval training proving to be the most efficient. While you can still perform these runs on a flat treadmill, HIIT running workouts are a lot easier on a manual curved treadmill. Instead of adjusting the speed and potentially losing your balance and hurting yourself, you can just slow your run on a manual treadmill to go between your sprints and jogs.

Why are Curved Treadmills so Expensive?

Compared to a traditional treadmill, the curved treadmill cost is usually a lot higher. This has to do with the overall construction of the machines, as well as the tremendous workout you can get by using one.

Here are a few manual treadmill options that are a great alternative if you’re looking for something a little more cost-effective, while also ensuring a great workout.
