Bowflex SelectTech 552 Adjustable Dumbbells
Integrating dumbbell exercises is a great way to build muscle and thus up your metabolism. Instead of filling a home gym with racks of weights, Bowflex's SelectTech 552 dumbbells offer a wide range of resistance in a single, compact package. Wheels on either end of the dumbbells spin to adjust the weight, from 5-52.5 pounds, with 2.5-pound increments up to 25 pounds, and 5-pound increments thereafter, replacing 15 different sets of weights. They sit in handy storage sleds that hold any extra weight when not in use and pair perfectly with the matching stand.
