What is a curved treadmill

Unlike regular treadmills, curved treadmills feature a concave design and are nonmotorized, meaning that you control your pace by adjusting your speed and stride rather than by changing settings on the treadmill. Since they don’t need to be connected to a power source, curved treadmills can be set up almost anywhere and often require less maintenance than motorized treadmills. In addition to saving energy, curved treadmills may offer several other benefits, especially when it comes to preventing injuries and improving your form (1, 2). That said, running on a curved treadmill is generally more challenging and may take some getting used to. It typically requires you to expend more energy and causes you to run a little differently than you would on a conventional motorized treadmill (1, 3).

Benefits of curved treadmills

Curved treadmills don’t have motors. They’re propelled solely by the motion of your body, which makes them a convenient and energy-saving alternative to regular treadmills. They can also help increase the intensity of your workout and boost the number of calories that you burn. One small study in 13 male runners found that running on a curved treadmill for 4 minutes increased heart rate and oxygen consumption significantly more than running on a motorized treadmill (3). According to one review, running on a curved treadmill may also improve your running gait, posture, symmetry, and balance (1). Not only can improving your running technique enhance your performance, but over time it may also help reduce the amount of energy that your body requires to run at a certain pace (5). Furthermore, some research suggests that running or jogging on a curved treadmill can reduce the impact on your joints to help prevent injuries (6).

Frequently asked questions

Is it harder to run on a curved treadmill

Because curved treadmills are self-powered, it can be more challenging to get started and maintain your momentum. They also operate quite differently than motorized treadmills, so it may take some time to get used to a curved treadmill if you’ve never tried one before. Still, many people prefer curved treadmills because they can increase the intensity of your workout and boost the number of calories that you burn (7).

Are curved treadmills better than regular treadmills

Compared to regular treadmills, curved treadmills can help you burn more calories and reduce the impact on your joints (8). However, they are typically more expensive and bulkier than regular treadmills. Curved treadmills also have fewer models available and offer fewer training and customization options.

Who are curved treadmills for

Curved treadmills may be a good option for people hoping to improve their gait, decrease strain on their joints, and increase the intensity of their running routine. Because they aren’t motorized, they may also be a good choice for people looking for a durable and energy-saving alternative to regular treadmills.

The bottom line

Curved treadmills are a great addition to any home gym. They can not only ease the strain on your joints but also help you burn more calories, save energy, and improve your gait. By considering factors like the price, size, and available training options, we’re confident that you’ll find the right product for your running needs. Last medically reviewed on September 28, 2022
