Who the Woodway Curve is for, in our reading of the spec sheet: Facilities and performance gyms that want Woodway’s slat-belt curve and do not need a wall outlet. Skip it when Home buyers who need a published consumer MSRP on the current Curve page — Woodway does not list a price there.

Who the AssaultRunner Pro is for: Home or garage athletes who want reinforced uprights and a larger console than Classic on the same 17x62 in curved deck. Skip it when Users over 350 lb (Elite is the 400 lb model) or anyone who needs motorized incline/speed.

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.

This page does not say either product was used, assembled, or worn-in by FitScout. Sources are the manufacturer URLs on each spec row. If a maker updates a dimension after 2026-10-14, the as-of date is the tell.
