We at Fitness Superstore only carry the best Treadmills on the market - the same ones seen at all health clubs and gyms today. These include the Life Fitness Treadmill, the Precor Treadmill, and the Woodway Treadmill. Other Treadmills work for walking or low speed workouts but beware! Running on lower quality treadmills can be dangerous, as they are flimsy, and they are not made with the shock absorption features that the best ones are made with. Don't buy the Sporting Goods store knockoffs. Buy the most trusted brands available at Fitness Superstore - at a price that you can afford.
