Who the Horizon 7.0 AT is for, in our reading of the spec sheet: Home runners who want Bluetooth FTMS app control (including Peloton metrics) and Apple Watch / Samsung Galaxy Watch pairing on a 20x60 in deck. Skip it when Users over 325 lb, or anyone who needs a published drive-motor horsepower figure — Horizon does not list motor HP on the 7.0 AT page.

Who the Horizon 7.8 AT is for: Heavier or sprint-focused home runners who want a 22x60 in deck, 9.3-inch color TFT console, and Bluetooth FTMS without a locked-in class subscription. Skip it when Buyers who need Apple Watch GymKit — Horizon’s comparison table lists that only on the 7.0 AT — or who need a published drive-motor HP rating.

If ceiling height is the constraint, prefer the shorter published frame and then run Will-It-Fit with your ceiling, your height, and the exercise. HAJEX’s standing-press rule of thumb is height × 1.33 plus about 9 in for full-size plates. A rack that “fits the room” on assembled height can still fail a pull-up if there is not about a foot above the bar.
