Who the Bowflex SelectTech 552 is for, in our reading of the spec sheet: Lifters who want a manufacturer-published 5–52.5 lb dial pair that replaces 15 fixed weights in one compact tray-based set. Skip it when needs more than 52.5 lb per hand or a single uniform increment across the full range.

Who the Bowflex SelectTech 1090 is for: Lifters who need a manufacturer-published 10–90 lb dial pair that replaces 17 fixed weights. Skip it when needs a starting weight below 10 lb or increments finer than 5 lb.

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.
