Open-Box — Two great machines in one. Ideal for people who are sitting a good portion of the day. Sitting for long periods of time is not the problem, it's being stationary while standing or sitting that creates problems. The mini elliptical will fit comfortably under a desk and you can get your legs moving while typing, talking on the phone, or reading. Want to turn up the workout while on break, switch into stand up mode, add some arm weights and burn even more calories. Burns up to 300 calories while sitting and even more while standing. Converts easily from stand up to sit down mode. Easy to move with a top handle, a front handle and rear wheels.
