Core Home Fitness Adjustable Dumbbell Set review

Core Home Fitness uses a twist-handle mechanism: a simple twist of the handle changes the weight, with no knobs or levers. Each dumbbell adjusts from 5 to 50 lbs in 5 lb increments, and a window on both handle ends shows the selected weight. At 14.5 by 7.9 by 7.5 inches per dumbbell, it is shorter than either Bowflex set, a real advantage in a small room or closet. The limits are the 50 lb ceiling and the lack of 2.5 lb steps, which makes small-muscle exercises jumpier than on the SelectTech 552. Core offers an optional app at $11.99 per month or $99 per year; the dumbbells work without it. The pair cost $399.99 when we checked, or $469.99 with the matching stand, and the warranty covers parts for 2 years.
