This Bally 5-lbs Dumbbell Set is ideal for beginners who are interested in weight lifting or for people who perform cardiovascular exercise. They can be used to give your chest, back, shoulders, forearms, biceps and triceps some exercise to gradually strengthen and sculpt them to ascend onto heavier weights. On the other hand, when combined with power-walking, step-training, yoga and physical therapy they will achieve an adequate cardio workout. This pair of exercise dumbbells have a vinyl coating making them easy on the floor and quick to clean. Each vinyl dumbbell has a unique design that prevents it from rolling meaning they are convenient to store.
