How to Choose the Best Curved Treadmill


Regarding the size of a curved treadmill you can buy, it's important to consider the space you have available. By definition, these treadmills are less compact than motorized versions; however, there are curved treadmill models that are designed slightly smaller. Some also have built-in wheels so you can move them around as needed.

Weight and Weight Capacity

If you plan on keeping your treadmill in one place, you may not have to take into consideration the weight as much as someone who wants to move it around. All of the treadmills on this list start at around 160 pounds and weigh up to 325 pounds. Typically, a more compact treadmill will be lighter, but since the frames are made of steel, they're never going to be super light.

When thinking about what weight capacity you'll need, consider how much you weigh and also whether you plan to wear tactical gear while you train. If you're closer to a weight capacity, with or without gear, it's a good idea to consider a curved treadmill with a higher capacity.


Even though the curved treadmills are more simplistic in design than motorized treadmills, they still offer some great features. Many come with built-in programming, while others just track the basics on their display. If you like to keep water or other items within reach, it's probably a good idea to look for a curved treadmill with storage. Handlebar size and styles vary as well, so think about what will be comfortable and useful for you.

In addition to the cosmetic features mentioned above, the design of the belt is important. A good quality belt will reduce the impact on your joints as you run and also move smoothly no matter what speed you choose. Some brands even allow you to customize your belt, which is an excellent option for those who want to train on turf or barefoot.

Benefits of Curved Treadmills

A curved treadmill can provide many benefits, including helping you improve your running form and posture. The shape of the belt encourages you to run on the balls of your feet, and that combined with the belt can absorb the shock from your landing so there is less stress on your joints. If you are leaning forward slightly, hunching over, or not bracing your core, the belt will move to force you to maintain control with proper posture.

Since the belt is self-propelled, you don't need to plug it in, which saves energy. You also don't need to worry about where the nearest plug is located. In fact, many athletes like to use curved treadmills outdoors. No motor also means you don't need to worry about motors going on the fritz. You may also burn more calories than with a motorized treadmill because you have to exert extra force to propel the belt.
