The California Fitness SM12 Stair Climber Stepmill provides a fantastic low-impact yet robust cardiovascular workout by meticulously simulating the motion of climbing real stairs, step by step. The commercial-grade SM12 stepper targets major lower body muscle groups, including quadriceps, hamstrings, and glutes, and features a deep step-surface for a comfortable step and safety. Designed for the fitness enthusiast who wants to burn more calories while toning their lower body with every step, the SM12 stepper’s revolving staircase offers a natural step pattern to build muscle where it really counts, with the feel of climbing real stairs.
Ever wonder why the more sophisticated treadmills offer an upward incline? The answer is simple enough. It's because the cardio benefits of carrying your own weight uphill hugely outstrip those of pounding away on the flat. Gravity is so strong that in climbing just 1 meter, you expend a big 9.8 Joules of energy for every kilogram of body weight. A StairMill is not the same as a 'Stair Climber'. A Stair Climber attempts to mimic the natural movement of your feet by use of a linear sliding motion of two narrow footplates. On a StairMill you climb free on the full width steps of a never-ending staircase, your feet, legs, hips, and torso moving in their own natural way.
A Stairmill - Not a “Stair Climber". Most machines labeled “Stair Climbers” don’t actually climb stairs. They lock your feet onto two separate treads that pump straight up and down—forcing an unnatural, linear motion that bears little resemblance to real stair climbing. A Stairmill changes everything - Its rotating steps let your feet follow the body’s natural curved stepping path, just like true stairs. The result? Deeper muscle activation, smoother movement, and dramatically better toning. This isn’t stepping in place. This is climbing—done right.
With safety in mind, the resting foothold steps on the SM12 stepmill are designed to allow easy step-up or resting action at the lowest possible point for easy user access. The intuitive, bright, easy-to-use console allows you to alternate between different speed levels for interval training.
