The curved treadmill is a type of running machine that requires no electricity. Its curved running surface places a greater demand on the user compared to a traditional motorized treadmill
The design encourages you to run on the balls of your feet, which in turn reduced the impact on joints and improved running performance. There is more core and trunk engagement due to the need to run at an ergonomically correct angle.
By minimising the vertical displacement of the body's centre of mass (COM) on the curved treadmill there is a coinciding increase in energy expenditure
