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.

    Stairmaster SM3 Stepmill

    Key Features

    • 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.

      • Heart Rate Monitoring: Heart rate pulse grips on the handlebars provide feedback throughout your workout.  Console also includes a built in receiver for Polar compatible telemetry heart rate monitoring (chest strap not included).
      • Reading Rack and Water Bottle Holder: Built-in reading rack keeps reading material at the perfect viewing angle.  Convenient water bottle holder helps keep you hydrated and allows easy access without interfering with workout space (water bottle not included).


      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.

      If you're looking to burn calories, lose weight and strengthen and tone major muscle groups, stair climbing provides astounding results. If you're willing to put in the work, it provides the results!

      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.

      Ask a Question
    • Why Choose Cardio Online?

      You’ve clicked on this page because you’re smart…

      How do we know that?


      You’ve come here because you need top quality fitness equipment and you want to know whether we're the place that will deliver what you want in return for your hard-earned money. 

      That makes you smart because you’re not going to spend your cash on just any piece of fitness equipment. We get the feeling you want to invest in the best quality fitness equipment in Australia.

      And we’ll (not so humbly) tell you, we believe Cardio Online is the perfect choice for your fitness equipment purchase.

      In fact, we’ll give you 8 knockout reasons why we think you should shop with us and not one of our competitors.

      I’ll get to those 8 reasons in just a moment.

      First up, who the hell are we and why should you listen to us?

      My name is Tristram and I'm the Managing Director of Cardio Online.

      I've been around the fitness world for years and I've partnered with some of the best brands in the world to bring high-quality, world-class fitness gear direct to homes, gyms and PT studios across Australia.

      Like we said, there’s 8 reasons you should choose Cardio Online for your next fitness equipment purchase. Let’s cover off the first now...

      REASON #1: 100% customer satisfaction GUARANTEED (if you’re not happy then neither are we – simple as that)

      We’ll bend over backwards to ensure you are 100% happy and satisfied with your order and our world-class customer service.

      We want you to rave about your experience with us to your friends and family.

      But we know that’ll only happen if we treat every customer like you’re the most important customer in the world. And you are!

      Without you we wouldn’t be in this business. We’ve only got to where we are today by treating our customers to a level of service, you’ll rarely find online.

      We’ll literally bend over backwards to ensure your online shopping experience with us is one you’ll shout about to your neighbour or mates at work.

      See, we’re not one of those big box stores or marketplaces with a multi-million marketing budget. We’re a small Aussie business. Every single potential customer that hits our website is precious to us (that includes you).

      So, again, we’ll do everything we can to make sure you’re over the moon with your Cardio Online shopping experience.

      But let’s move on to reason number two…

      REASON #2: Five-star customer support. We’re just an email, phone call or live chat away. We’re here to help you day or night

      Let me tell you straight up…

      We’re ‘officially’ around to support you and help you out with your questions and queries between normal business hours (Mon to Fri, 9am to 5pm).

      But just between us…our team is normally up and about at ungodly hours helping our customers choose the right piece of equipment or fielding a service request.

      We understand a lot of our customers are busy individuals.

      Sometimes, you’ve only got time to peruse our website when you’re sitting down on the couch, chilling out after a hard day at work (maybe with a cold beverage in hand).

      Good news is, we rarely switch off.

      If you need a hand with anything. If you’ve got a question. Just tap on the live chat widget (at the bottom right of screen), email us ( or call us on (07) 3040 0660.

      Two reasons down…here’s the third…

      REASON #3: 14 day return policy (shop with confidence)

      We’re so confident you’ll love your Cardio Online product that we offer a 14 day return policy.

      In the highly unlikely event you’re not completely satisfied with your purchase inside those first 14 days, and the product your ordered remains in the same as-new condition it was when it was sold to you, then we may (under our discretion) accept a refund request.

      If you’d like to take advantage of our money back guarantee, please contact us within 14 days of receiving your order. If we accept your request we will send you a return authorisation number.

      We will refund the purchase price (less any shipping charges) once we inspect and accept the product.

      We reserve the right to refuse any refund if the returned product is different in any respect to the product delivered, shows any signs of misuse, or is returned to us without following our return policy.

      If we reject the product returned to us, we will send it back to you at your cost.

      All return postage costs for items posted back to Cardio Online for change of mind are at the customer’s expense.


      REASON #4: We’re crazy-competitive on our prices with our Price Match Guarantee. If you see a product on Cardio Online cheaper elsewhere, contact us and we’ll see if we can work out a deal

      That doesn’t mean we’ll always beat the competition on price.

      Some of the big-name stores bulk up big time on products. We’re still competitive…but may not have the margin to beat them.

      That aside, our prices are easily some of the best value you’ll find online.

      Plus, when you bundle several items together, we’re more than happy to chat about a bundle discount

      Hit us up and we’ll chat more about price (you can open the chat widget at the bottom right of screen and start a conversation).

      REASON #5: We offer Free Shipping to 99% of Australians, and yes most of you regional Aussies are included!

      How is that possible you ask?

      We we've partnered with one of the largest networks of freight depots in the country with over 160 depots nationwide!

      So even for those super heavy items (like pin-loaded strength machines that weigh 400 kg), we can often provide our customers with Free Shipping to their doorstep.

      For the folks in regional areas, we can ship your order to the nearest depot and having them complete the delivery locally, saving you hundreds in shipping fees!

      Find yourself at checkout and see a shipping fee? Reach out to us and we'll see if there's a better option, like free shipping to a nearby depot and collecting from there

      REASON #6: Every product you buy from Cardio Online is covered by a minimum 6-month local warranty and in many cases well over 12-month!

      Nothing worse than buying something online and it’s faulty, right?

      We feel ya!

      That’s exactly why every item we stock is covered by a minimum 6-month warranty, most are covered by 12-months and some are even covered by a RIDICULOUS 10 year warranty!

      If the product you ordered from us doesn’t work right, simply let us know and we’ll get it fixed for you under warranty.

      Or if we can’t have it fixed, we’ll provide you with a replacement item as soon as possible.

      Nearly there, here’s reason no. 7…

      REASON #7: Safe and 100% secure checkout. Your private details will never be shared

      Our shopping cart is fitted with SSL encryption.

      What the hell does that mean, you ask?

      Well, that simply means all your data is 100% secure when you shop on the Cardio Online website.

      We don’t save or share any of your payment details. Nor are those precious details stored anywhere on our website.

      So, there you have it. There are our seven big reasons on why you should buy all your sim goodies from us and not the competition.

      Remember, we always happy to chat with you at any time.

      Lucky last...number 8...

      REASON #8: The price you see is the price you get. No hidden fees, it really is that simple

      Would you believe it, some of our competitors are trying to trick our valued customers (including you)!

       they tack an extra 10% for GST and often whack you with a shipping fee as well!

      And if you try and return a product, they charge you a 15% restocking fee!

      Well I'll proudly tell you now that we don't play those games here.

      We stand by our customers and we're genuine. What you see is what you get.

      Our prices are all inclusive of any taxes

      No last minute fees during checkout.

      No nasty restocking fees for returns.

    • 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.
