Kickstart your weight-lifting journey with ProForm’s 12.5-pound Adjustable Dumbbell set, the conveniently compact strength-training solution for any home fitness enthusiast. A revolutionary Easy-Adjust Weight Selection system allows you to quickly modify your dumbbell’s weight in 2.5-pound increments from 2.5 to 12.5 pounds so you can spend more time focused on your workout and less time wrestling with collars, weight plates, and other inconvenient equipment. A durable steel construction will help your adjustable dumbbell withstand your most intense weight lifting sessions, and provides a sleek, effective counterweight for a variety of exercises. Target muscles across your entire body - focus on your arms with bicep curls and tricep extensions, isolate your shoulders and chest with a bench or military press, and build strength in your lower body by supplementing lunges, squats, and deadlifts with your compact ProForm dumbbell. A convenient storage tray is included with your purchase. Featuring molded grooves to provide a secure home for your dumbbell set, this storage tray also clearly indicates the total weight value of your dumbbell at each level of adjustment.
