MFT-410® 4 in 1 Multi-function Manual Treadmill

On a manual treadmill, the action of your feet against the deck moves the belt. The belt only moves if you move it. Both runners and walkers expend more effort on a flat belt non-motorized treadmill than on a motorized treadmill. This has fitness benefits as users can get their heart rates into a higher zone at a lower speed.
