NordicTrack T Series 6.5Si Treadmill vs ProForm Pro 2000
Quick verdict
Winner on Gym Score: ProForm Pro 2000 (73)
The ProForm Pro 2000 is the better treadmill in nearly every measurable way — bigger motor (3.25 vs 3.0 CHP), longer deck (60" vs 55"), 14" touchscreen with iFIT integration, and -3% decline that the Horizon lacks. The Horizon's only advantage is price (typically $400-600 less). If you can stretch the budget, the ProForm is the right answer. If you can't, the Horizon is a competent 2-3 year starter at under $1,000.
Choose the Horizon if your budget caps at $1,000, you walk or jog under 5 days a week, and you accept that this is a starter machine you'll replace in 2-3 years.

The real tradeoff
iFIT lock-in is real on the ProForm — the experience is designed around a $39/mo subscription, and the touchscreen feels half-useful without it. Add 5 years of subscription cost and the gap between the two machines widens significantly. Horizon offers passive Bluetooth pairing (works with third-party apps) without subscription pressure. Deck length is the other gap: 5" of belt length matters more than people realize once you're running 7+ mph.
Skip both if you want a no-subscription treadmill with serious warranty backing. The Sole F80 at /product/sole-f80 sits between these two in price and beats both on warranty length.
Buyer questions
Is iFIT worth $39/mo for the average user?
If you use it 3+ times a week for trainer-led runs, yes — the content library is large and the auto-adjusting speed/incline genuinely improves workouts. If you'll use it once a month, no — pure manual mode treadmills (Sole, Horizon) give better long-term value.
How does the Horizon hold up over 3 years of daily use?
Reports are mixed. Light users (walking, occasional jogging) typically get 3-5 years without issues. Heavy users (running 5+ days, over 200 lb) report belt and motor problems closer to 18-24 months. The 3.0 CHP motor is the weakest link.
Can the ProForm Pro 2000 fold flat enough for apartment storage?
It folds to a vertical position and locks, but it doesn't lay flat. Footprint is roughly 40"x35" when folded — needs a designated corner or closet, not a slide-under-bed solution.
