Dumbbell Weight Vinyl Coated 4 lb Single vs Amazon Basics Vinyl Coated Dumbbell Hand Weights, 4 Pounds, Pair, Pink

Buy the Amazon Basics pair if you want two matching 4 lb dumbbells for light strength work and toning. Buy the single vinyl-coated 4 lb dumbbell if you only need one weight for rehab or one-handed exercises. The Amazon Basics set has hex ends that stay put and a contoured non-slip grip; the single has a cast iron core and a size-specific handle. Owners of both styles report the vinyl holds up well indoors, but vinyl can crack if dropped on hard floors.

• Choose the single 4 lb dumbbell if you need one light weight for rehabilitation, physical therapy or one-arm work and prefer a cast iron core.
• Choose the Amazon Basics pair if you want two matching 4 lb dumbbells for balanced two-arm toning and hex ends that won't roll.
