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).

Commercial gym equipment ships by palletized liftgate freight, not parcel — and standard freight is free to any address in the continental United States.

Delivery options

Standard liftgate freight — free. The carrier lowers the crate to your curb, garage or loading dock with a liftgate; you move the equipment inside.
White-glove delivery & installation — $350 per machine. Our crew places, assembles, levels and tests the equipment, then removes all packaging.
Warehouse pickup — free from our Boca Raton, FL warehouse.

Handling & transit

Orders are handled in 1–3 business days and spend 3–7 business days in transit, so equipment typically arrives within 4–10 business days. Orders placed before1:00 PM ET on a business day enter the same-day handling queue. You'll receive tracking and a scheduled delivery window once your equipment ships.

Title and risk pass to you on delivery. Inspect the crate and note any damage on the driver's receipt before signing, then email photos within 24 hours. Undamaged equipment can be returned within 30 days — see Returns & Refunds.
