If you’re looking for an active work-from-home setup, the Lifesmart 3-in-1 Treadmill is worth checking out. It also comes with a desk attachment that lies across the rail and turns it into a walking work station, no standing desk required. Simple to UsePhotograph: Kristin CanningIn walking mode the machine goes up to 3.7 mph, and in running mode it reaches 7.5 mph. This speed range will work well for folks who don’t want to sprint on their treadmill or who don’t do a lot of interval training. It can handle up to 264 pounds, which is impressive for a treadmill that's this small.
