The Sperax Walking Treadmill is one of the more budget-friendly options that still feels sturdy for daily use. It’s compact enough to slide under a desk or couch, comes fully assembled out of the box, and has a quiet motor that won’t distract you (or your coworkers if you’re on calls). Speed range goes up to about 4 mph, which is solid for walking or a light jog, and the LED display keeps track of steps, calories, and distance. If you just want a simple, no-fuss walking pad to keep your body moving during the workday without spending a ton, this is a great pick.
