FAQs About Curved Treadmills
As you search for the best curved treadmill for your fitness goals, there are a few things to consider along the way.
Get your questions answered and learn about the features and functionality of curved treadmills in this FAQ section.
Q: What is the point of a curved treadmill?
Curved treadmills are designed for more natural human movement that is powered solely by the user.
It mimics outdoor running versus an electric treadmill, which can be jarring on the body and difficult to adjust to if you are new to running.
A curved treadmill has a slatted running surface that requires the user to propel it forward using their own strength and stamina.
Runners can burn more calories, improve their form, and engage more muscle groups, including the lower back and essential core muscles, that they need to power through intense workouts.
Q: Are curved treadmills better?
When compared to a traditional treadmill, a curved treadmill is different in a few ways.
For one, curved treadmills are significantly less harmful to the body’s important joints, like the knees, ankles, and hips.
This is because the rubber slats help to absorb the impact typically experienced from running outdoors on the pounding pavement.
Runners can adjust their own speed on curved treadmills, making them ideal for sprint training and high-intensity interval training.
Q: Do you run faster on a curved treadmill?
Most curved treadmills have no minimum or maximum speed because they are completely controlled by the person using the machine.
You set the pace without having to wait for the belt to catch up. This makes curved treadmills a great piece of equipment for sprint training and intervals.
High-intensity interval training, or sprint training, is a research-backed effective method for weight loss and fat burning. The faster you run on a curved treadmill, the more effort you are exerting and the more calories burned.
Q: Are curved treadmills harder to run?
Curved treadmills require the user to propel the machine forward; there’s no electricity or automatic tread involved.
In order for the treadmill to keep moving, the runner must stay in motion. This requires more energy exertion and engages every entire leg muscle in the process.
To increase the pace of a curved treadmill, the user has to exert more effort. For some, this makes curved treadmills a more challenging workout, but it is entirely controlled by the runner.
In time, you will build endurance and muscle mass in your legs through bodyweight exercises and lifting weights. At that point, using a curved treadmill for running will become easier but still challenging.
There’s also a slight learning curve when transitioning from a traditional treadmill to a curved one. The body and the mind have to adjust to the feel of the belt beneath the feet.
Q: Is a curved treadmill good for walking?
Walking on a curved treadmill is a great low-impact exercise that will strengthen the glutes, hamstrings, and quads.
Many people use curved treadmills as they get into fitness to establish proper running form while preventing injury or strain on the joints.
