The HCI Fitness ProStep 6000 features revolving steps rather than pedals, as well as some unique features that make this a distinctly user-friendly stair stepper. Each step is 6 inches high and 9 inches deep, so most users won't find themselves continually kicking the end of the step. The Step Lock system automatically stops when you shift to the bottom step, locking the steps in place to prevent them from revolving; you can then remain standing on the stairs while you program your workout information into the ProStep 6000's console. If you prefer, you can also choose to override the Stop Lock system.

The computer control panel is similarly user-friendly. The LED display shows six windows detailing profiles, time, calories burned, speed, heart rate and distance. Going from 30-120 steps per minute, the ProStep 6000 offers three workout programs (cardio, manual and custom) and includes a heart rate control option; heart rate is monitored via the grip sensors built into the stair stepper's handlebars. You can program the stepper so you exercise until you reach a target goal of either time exercised, number of floors climbed or calories burned.

The electromagnetic resistance system delivers a smooth, comfortable motion, and since your own body weight powers the stair stepper, the machine uses only a minimal amount of electricity; HCI Fitness claims the power consumption of the ProStep 6000 is equivalent to that of a 60-watt light bulb. Since you are supporting your own body weight while you exercise on the revolving steps of the ProStep 6000, a workout on this model will quickly elevate your heart rate, which makes for an extremely effective workout in a shorter period of time.

The ProStep 6000 has a relatively compact footprint of 44X26 inches. It is 68 inches tall, but you will need a ceiling height of at least 8 feet to accommodate this stepper. While the machine is sturdy and well constructed, we are a little disappointed with the mere one-year warranty, especially since the ProStep 6000 carries a hefty price tag. Despite its high price and the short warranty, though, we were impressed with the overall performance of the HCI Fitness ProStep 6000.
