StairMaster vs Incline Treadmill: A Cardio Results Guide

The world of fitness is filled with debates on various machines and techniques to achieve fitness goals.

These tools can aid in losing body fat, enhancing endurance, or simply breaking a sweat with a heart-pumping workout.

Today, we delve into a classic debate: StairMaster vs. incline treadmill — which path leads to your cardio paradise?

Whether you are a dedicated StairMaster enthusiast or a newbie to the treadmill, understanding the best machine for your objectives is crucial.

Armed with the right knowledge, every step you take can make a difference.

Do They Work the Same Body Muscles?

When you use the StairMaster or stair climber machine, you activate all major leg muscles: quadriceps, hamstrings, calves, and glutes.

You may also engage your core and hip flexors, enhancing body strength and definition while improving balance and stability.

On the flip side, the incline treadmill offers a more evenly distributed challenge on the legs, simulating a gradual hike up a mountain trail. Depending on the incline level, you may target more on your glutes, hamstrings, and calves.

By not holding onto the handrails, you can intensify the workout for those muscles. Additionally, apart from the legs, you also activate core muscles to maintain balance and alignment.

What Are the Benefits of Incline Walking?

Inclined walking, a key aspect of the incline treadmill experience, offers a plethora of advantages:

What Are the Benefits of Staircase Walking?

The unique movement of a StairMaster workout also comes with numerous benefits:

• Provides high-intensity interval training (HIIT) potential, especially when incorporating speed intervals, boosting cardiovascular endurance in less time.


• Targets a specific group of muscles (leg and abdominal muscles), maximizing your outcomes.


• Offers lower joint impact compared to running, making it ideal for individuals with mild joint problems or those in recovery from injuries.

How To Choose Based on Your Goals

If calorie burn is your aim, either machine works well. However, remember: the effort you put in determines the results you get out! Speed and incline play a role in the number of calories burned.

Nevertheless, there are differences between the two machines to consider:

Workout goals:

• Incline treadmill: Ideal for enhancing endurance—the duration you can comfortably exercise. Walking on an incline also helps build leg strength.


• StairMaster: Great for high-intensity cardio, working at 80-95% of your maximum heart rate in short bursts. It also aids in building strong glutes and calves.

Impact level

• Incline treadmill: At a low speed and incline, it typically offers a low-impact workout that is gentler on the knees and joints. Running at higher speeds on steeper inclines increases joint impact.


• StairMaster: Also categorized as a low-impact workout. However, it can strain the knees and ankles due to the leg bending and extending motion. The impact on joints from either machine depends on the workout's intensity and difficulty.

Size and accessibility

• Incline treadmill: Typically larger and requires more space, although some models can be folded. Commonly found in most gyms.


• StairMaster: Generally more compact, making it suitable for smaller rooms. Widely available in gyms.

Workout variety

• Incline treadmill: Versatile for various workouts like walking, jogging, or running. Adjusting the incline allows for variation.


• StairMaster: Primarily focuses on stair-stepping motion, which may feel repetitive.

Skill level

• Incline treadmill: Beginner-friendly yet challenging for those seeking a tough workout.


• StairMaster: May require an adjustment period as you get accustomed to the stepping motion. While some may find it more challenging, it is suitable for all skill levels.

The Bottom Line: Both Machines Further Your Fitness

There is no right or wrong choice when it comes to selecting fitness equipment. The "best" machine is the one that aligns with your specific fitness goals. Experiment with each machine to see how your body reacts. Once you find the perfect match, your workouts will become something you anticipate.

Whether you are powering through a challenging session on the gym treadmill or climbing the StairMaster in the comfort of your home, the key is to keep moving.

Don't confine yourself to just one machine — diversify and attempt different exercises to continually challenge your body and mind. Remember, even minor alterations in your routine can yield significant results.

As always, consult with your doctor before embarking on any diet or exercise regimen to ensure it is suitable for you.

Enjoy the journey and reap the numerous benefits of exercise, regardless of its form. So, go ahead and conquer those stairs or crank up the incline on the treadmill — your healthier self will express gratitude!
