Stairmaster SM3 Stepmill

Key Benefits:

  • Maximize your cardio efforts - Stair climbing raises your heart rate immediately. By lifting your body weight with every step, strength training is naturally built in.
  • Low Impact and High Calorie Burn - Moving your body weight uphill burns calories faster than just about any other cardio activity.
  • Increase Core Muscle Strength - Maintaining balance engages core muscles with every step.
  • Tone and Sculpt Your Entire Lower Body - High repetitions are famous for building lean muscle and burning fat.


  • 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.

    • 10 Programmed Workouts: Quick Start, Manual, Steady, Mystery Challenge, Build, Bell Shaped, Calorie Burner, Fat Burner, Heart Rate Zone Trainer and Heart Rate Intervals provide a wide variety of workouts.
    • Blue Backlit LCD Console: Easy-to-read blue backlit LCD console displays time, watts, calories, heart rate, level (1-20), floors per minute, segment time, floors climbed and workout profile.
    • Take the Stairs: Revolving staircase with 6” high and 9” deep steps duplicates the workout of real stair climbing.  Staircase revolves at speeds varying from 26 to 162 steps per minute.
    • Choose Your Goal: Training goals can be set by Time Goal (5-180 minutes), Calories Goal (50-999 calories) or Floors Goal (7-999 floors).
    • Safety Stop Sensor: Automatic safety stop sensor located at the base of the steps will stop the stairs immediately when triggered.

      The StairMaster StepMill SM3 is designed after its "big brother" Stairmaster Gauntlet 8, providing users with the same high-intensity workout and exceptional experience but in a more compact, space-friendly unit for those with space limitations.

      The StepMill 3 offers the core mechanics of our commercial model wrapped in a stylish look and enhanced functionality to create a "high reward" next-generation experience for light commercial and home use.

      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.

      Stairmaster SM3 Stepmill

      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.

      It's awesome, we love it!

      We're loving the stairmaster, it's really good and we use it all the time. We had to set it up ourselves because the delivery was only to the driveway but that was fine. It was an easy process. Really happy with it.

      Just what I wanted

      Getting to the gym was difficult due to our hectic schedule. My favourite machine was the stair climber. Cardio Online had what I wanted and they were excellent in talking through what I had in mind. I cancelled the gym membership and bought the Stairmaster StepMill 3. Now I can workout on my time schedule. It's a good and stable machine but is narrower than the bigger Stepmill in the gym. Took a bit of getting used too but now I love it.

    • Dispatch Timeframes

      We strive to dispatch orders as quickly as possible, that's why we provide Next Day Dispatch on the majority of orders. Orders generally take 1-2 business days to clear from our warehouse, with 95% of orders dispatched within 1 business day. However some products require additional packing and handling prior to dispatch and therefore take longer to process. These can include:

      • Boxing bags - boxing bags are made to order and filled prior to dispatch. Due to the additional time required to fill bags, there may be a backlog of orders being processed. Consequently, delays in dispatch may occur during peak times (eg. Black Friday, pre-Christmas)
      • Heavy items - Bulky items and large orders are required to ship on pallets and often require additional packing prior to dispatch. 

      Shipping Timeframes

      Shipping time frame will vary depending on your location and the items you have ordered, but a general range is 1-7 business days from dispatch. Capital city metro areas can generally expect shipping times between 1-3 business days. Inner regional metro areas can expect shipping times between 3-5 business days. Shipping to outer regional areas can expect shipping times between 5-14 business days. 

      Free Shipping

      Our Free Shipping policy applies to most orders over $100 however charges will apply if shipping to more remote locations or if delivery requires a greater level of involvement by the courier eg. provision of a tailgate truck. If your order meets these criteria, we guarantee Free Shipping direct to your door with our "Leave Safe Home Delivery" option.

      All deliveries are to curbside only eg. garage or front door. Due to courier regulations and rules, delivery operators are not allowed to transport items beyond the front door.

      If you require assistance in transporting your product into the house, upstairs or similar, please contact us prior to delivery and we will happily arrange for assistance from our national network of third party specialist handymen. All handymen are vetted by us to ensure only the highest level of customer service and professionalism is provided.

      A number of our products are heavy and bulky items, and as such there are some restrictions to our Free Shipping policy. For items over 40kg, these restrictions are as follows:

    • - Items over 40kg are shipped on pallets and therefore come under additional courier restrictions. Consequently, we are only able to provide Free Shipping of palletised orders to commercial addresses or to the nearest depot.

    • - Delivery of palletised orders to residential addresses are subject to an additional service fee from our couriers for the provision of heavy duty tail-gate trucks and associated extra labour.


      The receiver will be contacted prior to delivery to arrange a suitable delivery date and time. Deliveries are scheduled for either an AM or PM slot on any given day.

      This service utilizes power tailgates with two-man crews or crane trucks when required and this is included in the quoted price. All goods in excess of 40kg in weight are palletised.

      Delivery is to front car port, driveway, doorstep or wherever practical depending upon site access. Drivers are not permitted to move item(s) within the residence or around the property due to OHS reasons. Please contact us at the time of your order to arrange for our in-home set-up and installation service.
      This service assumes reasonable and safe access to the site is available. Overhanging trees, steep driveways, unsealed driveways, narrow driveways or streets or an unforeseen obstruction may deem the delivery unavailable.

      If your delivery address is a regional postcode, please contact us to see whether the Residential Delivery option and/or our in-home installation service is available in your area. If the Residential delivery option is unavailable, we will ship to the nearest depot or alternative commercial address.


      This service is available Australia wide for consignments containing individual item(s) less than 40kg in dead weight.

      In utilizing this service the sender is acknowledging the carriers right to leave the goods at the recipients site without obtaining a POD signature. Where the item is left will be at the discretion of the driver. If the receiver happens to be home a signature may be obtained by the driver.

      For Leave Safe Home Deliveries, you cannot request the driver to ring customer prior to delivery. They simply will not call your customer because in booking this job, you are authorizing the driver to leave the goods in a safe area if your customer is not at home. If you would like us to call your customer prior to delivery, you will need to book a standard home delivery.

      Freight Warranty: For those customers with freight warranty, your freight is still covered whilst in transit for loss or damage. If your consignment is lost or damaged after confirmation of leave safe ("Driver POD" or system "Delivered" status) then your freight warranty coverage is void.


    • Freight costs vary for each buyer depending on their post code/location.
    • Deliveries cannot be sent to a post office box as we do not use Australia post.
    • Couriers can only deliver Mondays to Fridays, 9:00 am to 5:00 pm only. Delivery windows are for AM or PM delivery.
    • We are unable to take requests for deliveries on specific days or specific times of the day. Delivery timing is at the sole discretion of the courier and can be subject to many factors making such requests impossible to meet.
    • Delivery charges are quoted as “curbside delivery” which means as close to your premises as practical for a truck and to the ground floor.
    • Larger items and pallets must have someone home to help unload. Due to WH&S regulations, courier drivers cannot be forced into lifting items over 20kg. If you require assistance in this regard, please contact us to arrange for a specialist handyman to transport your product into your desired location. We also offer our in-home installation service.

    • It is your responsibility to advise us:

    • If someone will be available to sign for delivery.

    • If there somewhere safe it can be left if no one is home (e.g. around the back of the house)

    • If the address is a business address. If so we will require the information regarding the business hours and the name of the building.

    • If you say you will be home and miss the delivery, you will be required to pick up your delivery from the freight companies depot. Alternatively, we can arrange a re-delivery however this will incur a charge depending on the size of your order.

    • We cannot advise you the exact day and time delivery will occur however, we will email you the tracking details and the freight company contact details and they can provide you a better estimation of the time.

    • If you request that the freight company leave a card and return your order to depot in the instance that you are not home, you will be charged a fee if you request re-delivery.
