Bowflex SelectTech 1090
Strengths
- +10-90 lb in 5 lb increments — covers most adult home-gym strength work
- +Single dial swap, ~3 seconds between weights
- +Replaces ~17 fixed dumbbell pairs in one footprint
- +Genuinely durable plate stack — the failure point on dial dumbbells is the locking pin, not the plates
- +JHTNA continues sales + warranty post-acquisition
Weaknesses
- −Sold per unit — a pair is two purchases (~$1,000 total at list)
- −Heavy single unit (~95 lb each) is not move-around-the-house friendly
- −Wider handle than 552 may feel awkward for smaller hands at light weights
- −Plastic plate skins can crack on hard drops — these are not bumpers
- −Long-term parts-availability question post-Chapter 11 — verify warranty terms at purchase
