Walking and Running Pads
Walking and running pads, often sold as 2 in 1, work as a low walking pad with the handle down and as a small treadmill with it up. Walking mode usually stops at 6 km/h; running mode goes to 10 or 12 km/h.
For regular jogging, look for a motor of 2.5 HP or more and a belt at least 100 cm long. Taller runners should check the belt length carefully.
