    StairMaster HIITMill X Non-Motorized Incline Treadmill

    The HIITMill by StairMaster is a self-powered, non-motorized treadmill with fixed incline designed to develop speed, strength, and explosive power when used in a HIIT High Intensity Interval Training Program.

    The StairMaster HIIT Mill X will deliver an effective resistance training platform that drives up metabolic intensity and captures the benefits of speed and agility training, lateral training and sled training.

    Users can now safely push, pull, drive and sprint with the resistance of a sled but work within a smaller footprint. The HIITMill is aesthetically appealing to athletes at all levels of sport - professional, college, CrossFit, and UFC athletes.

    The HIITMill manual treadmill also invites simple activities with little to no learning curve such as walking on an incline, running hill sprints, or hiking with light resistance for general cardio training.

    One of the biggest trends in the fitness industry is High Intensity Interval Training, commonly known as HIIT. This training protocol involves repeated bouts of high intensity effort followed by varied recovery times. HIIT workouts are now used not just in athletic performance training centers, but also in crossfit boxes, personal training studios, and health and fitness clubs.

    One of the most popular and effective high intensity activities is pushing or pulling sleds loaded with weights to develop leg power and cardiovascular fitness. Because the indoor use of sleds requires a significant amount of space covered with artificial turf, it is impractical for many training centers and fitness clubs to offer sled-based activities. The HIITMill X will provide the means to benefit from sled activities without the need for the extra turf covered training space.

    Another popular exercise performed during HIIT workouts is the farmers walk or farmers carry. This strongman exercise is commonly executed using torpedo-like carry bars with raised handles which are loaded on each end with Olympic plates for bumper plates for heavy load resistance. The user lifts the farmers walk handles and moves forward under a heavy grip load. This hybrid exercise used for General Physical Preparedness (GPP) and Specialized Physical Preparation (SPP) will tax and strengthen your grip, upper body, and lower body to their physical limits.

    Similar to sled training, farmers carry training takes up valuable space inside a facility as it requires an open lane void of equipment or other clutter. By selecting the HIITMill X with Farmers Walk Carry Arms, facilities can offer their members and athletes a valuable tool to capitalize on this style of training within a very small footprint, thus freeing up usable space for other activities.

    Performance movements, high intensity exercises, and explosive training workouts that can be performed on the HIITMill include:

    • Hill walking
    • Hill walking with pushing resistance
    • Reverse hill walking (knee extension)
    • Hill running springs (no pushing)
    • High sled push
    • Mid sled push
    • Low flat back sled push
    • Lateral lunges
    • Bilateral farmers carry (HIITMill X only)
    • Unilateral farmers carry (HIITMill X only)
    • Reverse pulling / dragging (attachments not included)

    HIITMill Model Overview:

    The HIITMill features a standard treadmill running belt and longer handrails. The HIITMill will have less friction due to the thinner standard belt and this will allow lighter users to walk, run and perform hill sprints without the need to push off the forward handrails.

    The extended side rails and standard belt provide the opportunity for lateral drills, karaoke drills, and other "foot pattern" agility movements with decreased foot drag and increased side rail length for stability and safety.

    The HIITMill will allow users from 110 pounds and up to perform these types of activities that do not require pushing off the forward hand rails. All of the same heavy high resistance sled training and pushing drills can be done on the HIITMill X.

    • Full Commercial rated
    • Self-powered, non-motorized operation for walking, running, pushing, and pulling

    • Fixed deck incline at 11 percent grade for gravity assisted start-up - utilizes body weight to initiate flywheel motion
    • Extra-wide 23" belt width for lateral training and max stability under load
    • Multi-grip hand positioning high, mid, and low options
    • Forward push rails feature narrow and wide vertical grips and high/low horizontal grips
    • Black and silver color combination with corrosion resistant powder coating for sweat resistance

    • Side handrail designs for safe ingress and egress
    • Portable design with oversized transport wheels and rear carry handle

  • 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.
