AND YOU THOUGHT OUR STAIRS WERE TOUGH

From the makers of the toughest workouts in the gym, comes the Throwdown HIITMill & HIITMill X. Unlike a standard treadmill, these machines are self-powered speed and strength training tools designed to build explosive power when used in a High-Intensity Interval Training program. These High-Intensity machines deliver an effective resistance training platform that captures the benefits of speed and agility training, lateral training and sled training. Users can now push, drive and sprint with the resistance of a sled, safely and with a smaller footprint. These easy to use tools allow users to drive up metabolic intensity and make for a more space efficient solution to alternative training methods. Gear up for one tough and rewarding HIIT workout that members will love to hate.

2025–2026 rebrand note: This Throwdown HIITMill 9-4870-KINTP0 is the rebranded version of the StairMaster HIITMill (New).

The GymGo promise

Every unit we ship is covered: Full Manufacturer’s Warranty. New equipment carries the full manufacturer warranty, and GymGo handles the claim for you — one call, no runaround.

Read the full GymGo warranty terms →

Commercial gym equipment ships by palletized freight carrier, not parcel. After you place an order request, a GymGo specialist confirms the exact freight cost and delivery window for your ZIP code before anything is charged.

Choose your delivery level

Curbside freight — the carrier delivers to the end of your driveway or loading dock with a liftgate. You move the equipment inside. Lowest cost.
Room of choice — the delivery team brings the equipment into the room where it will live, including stairs where accessible.
Full assembly & installation — white-glove crews place, assemble, level and test the equipment, then remove all packaging. Recommended for treadmills and multi-station strength lines.

Lead times

Typical lead time: typically ships in 2–4 weeks — contact us for exact lead time. Transit adds roughly 3–10 business days depending on distance from our Hayward, CA warehouse. We call to schedule a delivery appointment before the truck arrives.
