Both Precor and Life Fitness produce sturdy, well-featured treadmills designed to handle vigorous home use, as well as commercial models that can endure constant use. If a particular feature is important to you, such as touch screen technology, choosing between these brands will be easy. Otherwise, with no clear winner between the two models on standard merits such as motor power and running surface size, prepare to choose based on intangible factors such as quality of customer service, or on simply which treadmill gives you the features you want at the best price.
