Whats the difference between running on a treadmill and running outdoors?
A treadmill “pulls” the ground underneath your feet, and you don’t face any wind resistance, both of which make running somewhat easier. Many treadmills are padded, making them a good option if you’re carrying a few extra pounds or are injury-prone and want to decrease impact. To better simulate the effort of outdoor running, you can always set your treadmill at a 1 percent incline.
