Other noteworthy characteristics include the 275-pound weight capacity, powder-coated steel frame, and automated safety stop sensor. Although this step machine is more compact than those seen in fitness clubs, it is nevertheless somewhat pricey and occupies a significant amount of floor space.

Reviews for the StairMaster StepMill SM3 are incredibly inconsistent. Some people gush over its performance, simplicity of use, and assembly time, which is somewhat lengthy. Some claim it is noisy and breaks down quickly after a few uses.


Design and Footprint

Because it weighs 63 pounds less than the STEPR and has wheels, the StairMaster SM3 StepMill is slightly easier to maneuver. Despite having a larger footprint (46″ L x 29″ W), this machine is still relatively small. Like the STEPR, the SM3 is compatible with spaces with ceilings as low as 8 feet.

The SM3’s construction features an injection-molded plastic shroud and a steel frame, but its shape and muted colors give it an outdated appearance. Some people favor the slightly taller steps (6″ vs. 5.2″) of the SM3 over the STEPR since it makes for a more challenging experience regardless of speed.

The SM3’s wheels, lower weight, and comparably short breadth make it easy to maneuver. However, unlike the STEPR, it doesn’t have raise handles, which makes the operation a little more complicated.

Console display

The D-1 Console, which has a backlight for easy reading, is included with the Stepmill 3. You can watch several outputs on the display and navigate through several applications. These comprise height gained, time, speed, and calories burned, among other things.

Moreover, this device uses pulse grips and telemetry heart rate to measure your heart rate. The panel has seven buttons. With a single press, you can alter your exercise regimen with the red “Stop” and green “Quick Start” buttons next to the up and down keys.

This Stairmill offers twenty-five distinct workout options. It combines goal-based exercises with quick-start programs to help you reach your fitness objectives. Enjoy the brand-new “Landmark” challenge as well. At the base of the stairs is a safety stop sensor that, when activated, will cause a mechanism to stop the stairs in their tracks.

Quality and Comfort

The Stepmill’s propulsion and brake systems are electronically controlled. This implies that every user can work comfortably and predictably because the drive chain accurately regulates the speed at which the stairs ascend. Stairmaster has over thirty years of experience in the fitness industry, and this model has completed the CPAT and WFI StepMill® Fitness Tests.

Large, padded handles provide the utmost comfort when operating the equipment, and stoppers at the bottom guarantee that you won’t slip on any surface you exercise on.

Extras and Benefits

With the integrated reading rack on this machine, you may read up on a book or the most recent news. A water bottle holder is also included to keep you hydrated while working out.

The Stairmaster Stepmill 3 is the perfect home exercise equipment for toning your legs and buttocks. Each step burns more calories than a typical floor-based stepper machine. On a regular treadmill, walking at 1 mph is equal to walking at 6 mph on a Stepmill.

One of the most well-known patrons of the Stairmaster brand is the pop superstar Madonna, who has been utilizing their products for many years!

User Experience

Here is the StairMaster StepMill review by an owner

Andrea Jayne Vogt-Lytal from the United States states: During the pandemic, I missed having access to a stair climber. I love having one in my own home! I’ve read other reviews of people having many issues with their Stepmill not working properly. We’ve had ours for a little under a month, and so far our only issue is that we sometimes have to unplug it and replug it to reset the power.

(I just yesterday started turning it off completely when I’m finished using it, to see if that solves the problem.) I would estimate that between my husband and me, we’ve used the machine about 2-3 hours per week, over the last few weeks. The machine was not easy to assemble, so that requires patience and tenacity. But we are very happy with the machine so far.


An incredible piece of HIIT/cardio equipment, the Stairmaster Stepmill SM3 pushes you a little more complex than a typical treadmill.

You will both get toned and receive a cardio exercise in the HIIT style from this.
