Over the course of nearly five months, we lifted thousands of pounds of weight for hundreds of reps (in addition to researching the topic, interviewing experts, and comparison-shopping) to find the best set of adjustable dumbbells for at-home use. With a lightning-fast adjustment mechanism, a compact footprint, and a 5-to-50-pound load range, Core Home Fitness’s Adjustable Dumbbell Set is the set we think will work best for most exercisers.
