UNNMIIY Adjustable Dumbbells (2–22.5 lb per dumbbell, Pair, 5-in-1)

The UNNMIIY Adjustable Dumbbells offer a 5-in-1 multifunctional design that converts between dumbbells, barbells, kettlebells, and push-up stands. This pair features a detachable selector-pin mechanism with a weight range of 2–22.5 lbs per dumbbell (45 lbs total pair) and 2.5 lb increments. The handle combines a 5 mm steel tube with 20 mm thick foam padding and a non-slip ABS grip; plates are cement and iron-sand composite. The compact design occupies under 2 sq ft when stored. Built-in locking nuts aim to prevent slipping. Best suited for home-gym beginners and space-conscious lifters looking for progressive overload on a budget, though the light maximum weight limits advanced strength training.
