Why Adjustable Dumbbells
A full set of fixed dumbbells 5-50 lbs costs $800-1,200 and weighs ~550 lbs. Adjustable dumbbells replace all of that. The tradeoff: adjustment speed, durability, and feel.
Recall note: CPSC and BowFlex announced a June 5, 2025 recall covering BowFlex 552 and 1090 adjustable dumbbells because weight plates can dislodge from the handle. Verify model and recall eligibility before buying used, and stop using recalled units until the remedy is complete.
