Whether you can't justify dedicating the floor space to a full-fledged treadmill or are looking for an alternative to early morning jogs through unfamiliar neighborhoods when you travel, a portable treadmill provides the flexibility you need to keep your fitness routine on track. Although portable treadmills frequently aren't as sturdy as their less mobile counterparts and few offer a competitive features package, many are still more than functional when you can't use a larger treadmill.
Stamina InMotion II Manual Treadmill
If you're on a budget, the Stamina InMotion II is nothing but business. The no-frills treadmill isn't equipped with a motor, relying on your foot power to drive its belt, and its 42-inch belt is much smaller than those on other treadmills, which may limit your stride length. The lack of a motor and small belt translates into a lightweight -- a mere 56 lbs. -- that makes this treadmill one of the more manageable portable treadmills. Included in its frame is an electronic monitor that keeps track of basic functions, such as your distance traveled, the time you spend on the treadmill, your average speed and an estimate of the calories you burn.
Horizon Evolve SG Compact Treadmill
This slim treadmill boasts a 1.5-horsepower motor that's capable of driving its belt at speeds up to 6 mph. Able to fold down to a 10-inch height to be slipped under your bed, it's also capable of upright storage so you can stash it in a closet or behind a door. Its 45-inch belt is able to support joggers or walkers up to 250 lbs. in weight, while you can choose from preprogrammed workout settings or set the belt speed to your preference. The console provides heart-rate monitoring capabilities and built-in speakers so you can play from a portable music device.
Bowflex Series 7 Treadmill
Straddling the line between more traditional portable treadmills and stationary machines, the Bowflex Series 7 offers the muscle of a full-fledged treadmill and the fold-and-hide capabilities of a portable unit. Its 60-inch belt provides enough space for even the longest strides, and is driven by a 3-horsepower motor capable of pushing you to speeds up to 11 mph. Its belt is adjustable to add slope of up to a 12 percent grade to add extra challenge, and its built-in programming features 15 workout programs. A wireless heart-rate monitoring system keeps track of your exertion without the need to wear a monitoring device.
