Stairmaster SM3 Stepmill

For nearly 30 years, the StairMaster Stepmill has been called the toughest workout in the gym. And since climbing stairs is widely recognised as one of the most efficient and effective cardio and strength building workouts you can do, the Stepmill is still considered by many to be the perfect exercise machine.

Now you can bring that same toughness home with the new Stairmaster Stepmill 3.

The toughest workout in the gym, right in your home

The Stairmaster SM3 Stepmill is easy to recognise - it's the piece of cardio equipment that looks brutal compared to all the others, with a revolving set of 6-inch stairs that closely duplicates the workout of actual stair climbing.

Each time you mount the Stairmaster SM3, the unit's electronically controlled magnetic brake precisely controls the pedal descent, allowing a wide range of users to exercise smoothly within their comfort zones. The resulting step range of 26 to 162 steps per minute will strengthen your legs, boost your cardio, and challenge even the fittest of users.

    Key Benefits of the Stairmaster SM3 Stepmill

    Intense calorie burning for maximum results

    There’s no denying the impact that a good cardio session can have, particularly if you’re following HIIT principles that allow you to benefit from the body’s ‘after burn’ effect.

    The Stairmaster SM3 Stepmill is one of the few options that can allow you to achieve a truly jaw-dropping level of intensity, and the more intense your workout is, the more you’ll be able to push your limits and tap into this ‘after burn’ effect.

    Ultimately, this allows you to burn more calories in less time, which is ideal for people who are busy and don’t have time to spend hours on a treadmill.

    Fun, Unique Workouts to Keep You Motivated

    HIIT training is widely recognised for its many beneficial effects on the body, including mental health and wellbeing. In fact, HIIT has been scientifically proven to increase the body's production of chemicals that make us feel good.

    Pushing yourself to the limits on a Stairmaster SM3 stair climber gives you a challenge to look forward to each day. Plus, the sophisticated tracking tools available on the best machines from StairMaster make it easy to see how you’re progressing over time, which further lends motivation to each and every workout you undertake.

    Tone Your Lower Body and Build Leg Strength

    Toning your lower body is often a challenge, and even if you are running all day on a treadmill, there’s no guarantee that you’ll be truly strengthening your lower body versus merely losing weight and burning calories.

    However, the StairMaster SM3 engages your quads, glutes, calves, and hamstrings, making sure you nail every key lower body muscle group in one exercise.

    Furthermore, it can also help to work out your core muscles and general stability, so the simple act of stair climbing is very close to a full body workout.

    Improve Your Posture

    One of the more surprising aspects of stair climbing is the fact that it will generally improve your posture over time.

    Due to modern living circumstances, many people may have posture issues that they are unaware of, and this can wreak havoc with your long-term health and even affect your mental well-being, too.

    Unfortunately, many cardio machines only exacerbate the problem, particularly exercise bikes, which tend to encourage a hunched over posture which isn’t good for your lower back and spine.

    On the other hand, a stair climber quickly rewards you for keeping better posture, and it will help you develop the necessary core strength that’ll leak over into everyday life.

    After a few weeks of using a stair climber, don’t be surprised if you feel like you are standing a little taller and benefiting from better posture without really trying at all.
