Primo Fitness Stepmill vs. Life Fitness Powermill Climber vs. StairMaster SM916 Stepmill

Stairstep-based exercise equipment offer one of the most challenging workouts in the shortest time frame by engaging both cardio and strength aspects of a complete lower body workout.

We've chosen three machines to survey here that together represent a broad spectrum of what's available in the category at the "more economical" end of prices.

First, some of the benefits...

While working out for as little as 10 minutes can be beneficial you can burn up to 1.5 times your bodyweight in calories with each 30-minute workout on a stepmill. Because you never need to descend the stairs stepmills offer some the lowest impact cardio for the intensity of the workout available in the entire gym.

And naturally, some challenges...

Make no mistake: the size, weight and bulkiness of these machines means that they are more geared towards use in a professional fitness environment that in a home gym. For starters there's the height of the user when standing on the top-most step. A 6'+ male can easily be over 9' tall when on the top stair of these machines. That means a 10' ceiling is necessary in order to even feel comfortable using the machine.

Their weight means that USPS, UPS and FedEx are all out of the shipping equation and that it will need to be freighted to you.

All of their features mean one thing: this a complex mechanism and it's going to be more expensive to purchase, require setup to use, need adjustments and maintenance.

Finally, you'll notice the different names...

If you spend any time comparing all of the various models available in the stairstep-based exerciser category you will quickly notice that some of the manufacturer's has taken pains to create an entirely new name for what is essentially the same machine. While the category is known generally as "stepmills" Life Fitness calls theirs the "Powermill Climber" and Stairmaster, who could call them "the stair master" instead calls them "stepmills".

One of the main distinctions that the SM916 has is the ability to upgrade the console from a backlit LED to a 15" LCD screen and it's inclusion of 10 exercise programs not 6 as in the Stairmaster 7000PT (see comparison below).
