LifeOG 25 lb Adjustable Dumbbells (4–25 lb per dumbbell, Pair)

The LifeOG 25 lb Adjustable Dumbbell Set is a dial-selector pair (2 dumbbells, 50 lbs total) with 5 weight steps (4, 10, 15, 20, 25 lbs each). Adjustment is claimed at "1 second" via rotating dial on the dumbbell base—weight selections lock only when placed back on the base, then auto-lock when lifted via a dual-lock mechanism. Build is cast-iron plates wrapped in thick PE (polyethylene) outer coating, designed to resist cracking versus vinyl alternatives. Grip is 33mm soft-textured rubber. The set ships with a base/tray for storage and adjustment. Footprint is compact when racked (7.6" × 15.7"). Who it's for: home-gym beginners to intermediate lifters seeking space savings and quick weight swaps without the cost of premium brands like Bowflex SelectTech or NÜOBELL. The 5-lb increment jumps (4→10→15→20→25) are coarser than sub-5-lb-step premium rivals, and LifeOG is a lesser-known brand with limited third-party community validation.
