Horizon Fitness 7.8 AT Treadmill This Horizon Fitness 7.8 AT Treadmill is the flagship of Horizon's Studio Series folding treadmill lineup, built for runners and interval trainers who want a commercial-standard 22" x 60" deck without giving up floor space at home. An extra-wide, extended running surface and 3-Zone Variable Response Cushioning give every stride the flex and support of a studio-grade machine, while one-step hydraulic folding lets it tuck away between workouts. Horizon's RapidSync™ drive system and QuickDial™ speed and incline controls make fast interval changes effortless, and Bluetooth Fitness Machine Service (FTMS) connectivity streams live workout metrics straight into apps like Peloton, Zwift, and Kinomap on your own phone or tablet — no proprietary subscription screen required. Key Features Extra-Wide Running Deck: 22" x 60" surface with 3-Zone Variable Response Cushioning for a commercial-standard stride at any pace. QuickDial™ Controls: Roll-dial speed and incline adjustments plus one-touch Custom Interval Keys for no-delay interval training. RapidSync™ Drive System: High-response drive engineered for fast, smooth speed and incline transitions. 9.3" High-Contrast Color Display: Paired with a 16-digit alphanumeric LED window for at-a-glance workout metrics. Bluetooth App Connectivity: Transmits live metrics via Bluetooth FTMS to Peloton, Zwift, Kinomap, and Strava; includes a Bluetooth heart rate chest strap. Built-In Sprint 8 Program: 20-minute high-intensity interval workout designed to engage fast-twitch muscle fibers. One-Step Hydraulic Folding: Folds and unfolds in a single motion for easy storage between sessions. Heavy-Duty Frame with Aluminum Side Rails: Rated for a 375 lb max user weight. Media Controls & Built-In Speakers: In-reach playlist controls plus an audio in/out jack for on-deck audio. USB Type-A Charging, Accessory Tray & Water Bottle Holder: On-deck convenience for longer runs. Wide Speed & Incline Range: 0.5–12 mph speed, 0–15% incline. Feature Highlights QuickDial™ Controls Exclusive to Horizon's Studio Series, QuickDial™ replaces button-tapping with two roll dials — one for speed, one for incline. Roll forward or back and the change happens instantly, so runners can shift pace or hill grade mid-interval without breaking stride or losing focus on their workout. RapidSync™ Drive System RapidSync™ is Horizon's high-response drive technology, engineered to execute speed and incline changes faster than a standard treadmill motor. The result is a smoother transition between intervals and a more efficient run, especially useful during Sprint 8 or other HIIT-style programming where pace changes happen every 30–60 seconds. Who This Is For Built for home runners and joggers who want a studio-quality deck and interval-training controls without a subscription-locked console. Ideal for anyone already using Peloton, Zwift, or another streaming fitness app on their own device, and for households needing a treadmill that folds away between sessions.
