Bowflex Adjustable Dumbbells are essentially a micro-gym. In just two bars, they consolidate the functionality of a full rack of weights (2.5 – 52.5 lbs) — we’re talking upwards of 24 individual dumbbells. The weight is easily adjusted with a dial that controls a clever gear mechanism, and the dumbbells come with two storage strays. The compact nature of these guys makes them perfect for dorm life. We keep a communal set in the small hallway between our rooms and get a ton of use out of them. This product is a rare in that it checks off so many desirability boxes: sturdy, easy to use, space-saving, time-saving and money-saving.
