I use this treadmill about six to seven times a week for about an hour or more each time. It's smooth so I can walk, listen to music and read a book so I'm multi tasking on the treadmill With such a busy schedule it's hard to find time to get to a gym every day so I have the treadmill in the basement and I can walk or run in about the same amount of time that it takes me to get to the gym and back home. Plus I'm saving on the cost of high gas prices and the wear and tear on my car. So by the time you figure the savings on gas for a year, plus your travel time, you are well ahead of the game by purchasing this treadmill. proform tredmills
