Looking for the best curved treadmill to lower the impact and stress on your joints? Curved treadmills are made to ease the strain on joints and aid in physical rehabilitation. They feature a concave surface for running and they’re also non-motorized, and they come with the added benefit of increasing your cardiometabolic demands while letting you shed extra weight. We’ve compiled a list of the 9 best curved treadmills of 2024 to help you find one that meets your needs.

Viktoria Hamma, a chronic pain and weight loss coach, says, “Traditional treadmills are tough on your joints because they don’t require much muscle activation. Because the tread is powered it doesn’t require your foot and leg to push it backwards during the gait cycle. Curved treadmills are powered by you! Meaning your muscles push the tread and give you a better workout.”
