Here’s what to look for when you’re trying to decide which stepper is right for you:

Dependent and Independent Stepping Action.
Steppers are built to offer dependent (meaning that when you press down with one leg the other goes up) and independent (each leg moves separately) stepping action. Dependent steps are linked in a sense, whereas “independent units” provide a stepping action where one step isn’t controlled by the movement of the other, which means the motion can feel more natural and challenging. Many first time steppers describe the dependent action as “easier.”

Which is best? The speed and resistance can be adjusted to give you a similar workout, regardless of the type of machine stepping action you choose. You guessed it. Rather than rate one as better than the other, try both and decide which one you like the best and will use!

Frames, Foot Pedals and Other Things.
Look for a sturdy frame that doesn’t wobble, foot pedals or platforms that fully and comfortably support the feet during climbing, and smooth, reasonably quiet action throughout the entire range of motion. The stepper should also offer even resistance through the full range of movement. Choose a model with handrails and use them only for support and balance. Don’t “sleep” on them.

Drive Mechanisms.
This isn’t that complicated, so hang in there! High quality steppers utilize belts and steel cables, as opposed to chains, to drive the stepping motion. This results in quieter and smoother machines.

Look For Flywheels on Computerized Models.
Computerized climbers, like those found in health clubs or in high-end home fitness equipment, use flywheels to control the motion. The flywheel is propelled by the belts or cables when you apply weight during stepping. Flywheels work better than alternators--which you find on older equipment--because they help the machine work more smoothly.

Hydraulic Shocks.
The better manual steppers make use of hydraulic, oil-filled shocks, which extends the life of the machine and provides adjustable resistance. If your unit uses pneumatic, air-filled shocks and they fail, your machine is on hold until they can be replaced. Historically, air-filled shocks and their failure rate are higher. Both types can be replaced.

Features and Programs.
Some manual climbers have options that let you work your upper body, whereas some electronic models offer interactive heart-rate monitors that help you exercise in different target heart ranges, or computer programs that predetermine how hard you will work. Standard features usually include a monitor that displays total steps or “stories” climbed, calories expended and elapsed time. Decide whether you think these features will motivate and inspire you to continue working out on a regular basis.

Space.
Generally, steppers offer a “small footprint.” In other words, its base doesn’t take up much room in your house. Some can even be stored in small places, like closets.

Price.
Quality steppers, and the price of computerized equipment in general, has substantially lowered in the past few years. Do your homework, and you’ll be pleased to find that you can own this time-honored piece of exercise equipment for a fraction of the cost you might have expected.
