Dumbbells are the key building blocks of fitness whatever your goals may be, that's why it's important to select your ideal dumbbells wisely. The Reebok Dumbbell set in particular is ideal for those looking to tone their muscles and includes 2 x 1kg, 2 x 2kg and 2 x 3kg vinyl coated free weights, which can be stored away in the compact storage case provided. With a rounded square design, the dumbbells won't roll when placed on the floor, which is also ideal for plank upright rows and other exercises performed on an exercise mat with weights.
