But first, a brief synopsis before diving into the details.

When comparing the StairMaster VS treadmill, major muscle groups tend to overlap. Using both the StairMaster or treadmill for weight loss and cardio is viable, though muscle and strength development is greater with the former, while stair climbing typically gives a more intense exercise.

Stairmaster vs Treadmill Review

What Is A StairMaster?

StairMaster is a brand name for a type of cardio exercise machine known as a “stair climber” or “stair stepper.” As you could probably guess from the name, the purpose of the machine is to simulate climbing stairs as a means of working out. A stair climber utilizes a moving flight of stairs, while the stair stepper uses two pedals that move up and down alternately.

The most basic way to explain how it works is to imagine walking in place on a regular staircase escalator, except you’re allowed to adjust the speed and resistance level of the steps. Stair climbers are primarily designed to move downwards, which simulates climbing up the stairs, though there are models that can also move upwards to simulate downward climbing.

StairMasters are quite popular and most well-equipped gyms and fitness centers have them. There are also versions available for home use, which are typically more compact to save space. They’re quite popular due to offering a low-impact cardiovascular workout while providing high engagement to your lower body and core.

Additionally, the intensity of the workout can be adjusted by changing the speed and resistance settings on the machine, allowing athletes of varying fitness levels and workout goals to use them.

What Is A Treadmill?

Treadmills are arguably the most recognizable and commonly used cardio exercise machine. The main purpose of a treadmill is to simulate walking, jogging, or running indoors. They’re widely used in gyms and fitness centers, but there are also plenty of home-oriented treadmills that tend to be more compact and most importantly quieter.

A typical motorized treadmill is highly adjustable. Using the built-in control panel, athletes are not only able to track their progress but also change the speed, incline, resistance, and other settings.

With these settings, they can provide users with a wide range of controlled and convenient cardio workouts without having to go outside or worry about weather conditions.

Treadmills are quite popular because they’re as straightforward and intuitive as machines go. In essence, you simply step onto them and walk, jog, run, etc. and you’re working out. Many treadmills also offer built-in workout programs or the ability to set your own, allowing for a diverse and engaging workout experience.

Stairmaster VS Treadmill

So, is the StairMaster or treadmill better? By comparing the two, we can see there is plenty of overlap in workout and health benefits. However, exercise approach, variety, and difficulty can be much different depending on the settings you choose. Here’s a quick overview in table form:

Best ForMuscle developmentCustom cardio workouts
Movement PatternUp and down climbingWalking/Jogging/Running
Range Of MotionLowerHigher
Calorie Consumption (lower intensity)HigherLower
Calorie Consumption (higher intensity)LowerHigher
Muscle EngagementHigherLower
DifficultyHigher (higher exercise impact)Lower (range of approaches between speed and incline settings)

1. Movement Pattern

The movement pattern and range of motion (ROM) are different between the stair climber VS treadmill. Stair climbers utilize an upward (or downward) climbing motion, which can be difficult depending on your mobility and physical health.

Additionally, the range of motion is typically shorter, as there is less distance traveled by the muscles and the upper body remains unused for the most part.

On the other hand, treadmills primarily use a natural forward-moving motion such as walking or running, making them a bit more forgiving and user-friendly. Furthermore, the range of motion can be much greater in comparison to stair climbers, particularly when jogging or running, due to near full-body activation.

2. Muscle Engagement

There is plenty of overlap in muscle engagement between the treadmill and the stair climber. Primarily, they both work the lower body muscle groups and utilize body mechanics such as balance and stability.

However, due to the previously mentioned differing movement pattern and ROM, there are differences in muscle groups engaged and the intensity at which they work.

Treadmills primarily engage the major lower body muscles, including the quadriceps, hamstrings, glutes, and calves. In addition, they require activation of the hip abductors and adductors as well as the upper body due to arm swings necessary for balance and coordination.

The impact on the muscles is low and better serves for muscle toning, rather than creation. That said, this can be adjusted using incline and resistance settings.

As for stair climbers, the primary targeted muscles are nearly identical, with most focus again on the quadriceps, hamstrings, glutes, and calves. However, the up-and-down climbing motion of stair climbers or steppers creates greater muscle compression.

As you step up, the muscles contract to lift your body, and as you step down, they lengthen while still under tension. This eccentric (lengthening) and concentric (shortening) muscle action increases the recruitment and activation, leading to greater and faster overall development, particularly in hypertrophy (muscle growth) and raw strength.

3. Impact And Joint Stress

On the whole, both exercise types are considered low-impact, as they use your body weight for resistance, which you should be naturally accustomed to bar outstanding circumstances.

That said, due to the constant up and down pushing against your own weight, climbing stairs has a noticeably higher impact on the joints, particularly the knee, than walking. For this reason, people with joint issues, particularly the elderly, may prefer a treadmill over a stair climber for their daily dose of cardio.

Treadmills can, however, be adjusted to provide a higher-impact workout by increasing the incline or speed.

4. Weight Loss

Is StairMaster or treadmill better for weight loss? To answer this question one needs to understand what a metabolic equivalent of a task or MET is. MET is a unit used to estimate the energy expenditure or intensity of physical activities.

In simple terms, the higher the METs, the higher the energy requirement of a specific exercise, thus leading to greater weight loss.

According to the Compendium Of Physical Activities, slow-paced stair climbing has a coefficient of 4 METs, while fast stair climbing is worth 8.8. Research on the topic confirms nearly identical results.

Meanwhile, walking and running can go anywhere from 2 to 10 or more METs depending on the speed and incline. For example, running up the stairs is equal to 15 METs.

From this, we can conclude that, although treadmills are perfectly capable of aiding in weight loss, stair climbing generally has higher energy consumption rates.

Stairmaster VS Treadmill: Summary

Looking at the treadmill vs stair stepper, each machine has positive and negative aspects you should be aware of before making a purchase decision. So, is the StairMaster better than the treadmill or vice versa? Here are brief rundowns on each machine’s pros and cons, which are especially applicable when compared to each other.


  • Greater Muscle Development – thanks to the eccentric and concentric muscle action, stair climbing is generally better at developing raw strength, explosive power, and muscle size in the lower body. This makes it quite popular among athletes who want to develop their glutes and quads especially, but also hamstrings, calves, and core muscles.
  • More Compact – although they can be bulky, the general space requirement for a home stair climber is on the lower end amongst cardio machines, particularly due to lesser length.
  • Calorie Consumption – thanks to the more intense nature of their workout, stair climbers have a higher calorie consumption rate, particularly compared to walking and jogging. This metric only gets close when comparing a StairMaster VS incline treadmill max speed runs.


  • Limited Upper Body Engagement – due to the nature of the workout, muscle engagement is practically limited to your lower body. When climbing stairs, the upper body mostly remains stiff and the arms stay in place to help with balance and stability.
  • Less Accessible – stair climbers may present some accessibility limitations due to their vertical up-and-down motion and higher impact. Individuals with joint issues, limited mobility in the hips, or difficulties with balance and coordination may find these machines less accessible compared to other options.
  • Lower Movement Variety – while effective for targeting specific muscle groups, the repetitive nature of the movement of stair climbers can become monotonous over time. This lack of variety could potentially lead to faster exercise fatigue and may prompt individuals to explore alternative exercise options to keep their workouts fresh and engaging.

Pros And Cons Of Treadmills:


  • Exercise Variety – treadmills are arguably the most versatile cardio machine type. Motorized treadmills in particular tend to have a wide range of settings between the speed, incline, workout mode, etc.
  • Low Impact – unless specifically readjusted with resistance or incline levels, treadmills generally provide a lower impact workout than other cardio machines. This makes them more accessible to a wider range of users, particularly those that have issues with lower body joints and muscles.
  • Natural Motion – working out on a treadmill utilizes everyday movements like walking and running. This significantly lowers the learning curve necessary to use them and makes their exercise types more applicable to daily life.


  • Space Requirement – treadmills typically have a larger footprint than other cardio machines, due to the length and width necessary to safely perform the workout.
  • Noise Creation – although home edition treadmills have specialized features that reduce this issue, treadmills generally create more noise than the StairMaster. The continuous impact of the user’s feet on the running surface leads to greater vibrations and sound transmission through the machine’s frame. This can be particularly impactful to your surroundings if you plan to work out at home.

StairMaster VS Treadmill: When to Use Each?

So far, we’ve explained how each machine works, what the typical exercise experience looks like, and the benefits and drawbacks of a treadmill vs stair stepper aka climber. The next question is, when do we use each?

This choice will be most affected by your personal goals, exercise preferences, and health considerations. In short, it’s best to choose StairMaster for intense lower-body workouts and the treadmill for a range of exercises and overall cardiovascular improvement.

The StairMaster simulates climbing stairs, targeting the lower body muscles and providing a high-intensity cardiovascular workout. This type of exercise is best fit for muscle and strength development, particularly in the glutes, quadriceps, hamstrings, and calves, which are muscle groups important for your general fitness level and body aesthetic.

If you want to “feel the burn” but have limited time to exercise, climbing stairs is particularly good at calorie burn, muscle engagement, and cardiorespiratory development in shorter time frames.

Is StairMaster Or Treadmill Better For Weight Loss?

You can use either the StairMaster or treadmill for weight loss, but the results will depend on what type of workout, in terms of speed, resistance, and length, you perform. Stair climbing tends to outperform regular walking and jogging, but falls short of high-intensity runs, particularly if an incline is present. That said, the averages tend to even out and both machines are a good choice.

Is StairMaster Better Than Treadmill For Muscle Gain?

A StairMaster is generally better for muscle gain than treadmills, thanks to greater compression and activation. That said, some people may prefer the treadmill for its wide exercise variety.

Is StairMaster The Best Cardio?

A StairMaster machine can provide an excellent low-impact cardio workout fit for weight loss and muscle development. Having said that, is the StairMaster better than the treadmill and other cardio machines?
