40lb Adjustable Dumbells

Core Home Fitness 40lb adjustable dumbells are perfect if you want a flexible home-gym setup that supports consistent training without taking over your space.

Our 40lb adjustable dumbells are ideal for toning, muscle-building, and everyday strength work—especially for upper body training, accessory lifts, and full-body routines where you want quick changes and clean transitions.

One of the best parts about our 40lb adjustable dumbells is how they make workouts simpler to run. You can warm up, work, and finish using the same pair—then adjust weight between exercises in seconds.

That means less time searching for the next dumbbell and more time actually training, whether you’re doing circuits, supersets, or structured strength sessions.
