The square dumbbell has many advantages. Based on its novel design, sturdiness, security and affordability are all added bonus features. Because of that unique square shape, it is firmly set into your hand (so as not to accidentally fall). Firsthand, this makes those demanding workouts safer than you might think otherwise. Secondly, with the balance of its heavy sections at either end and middle, the weight distribution makes each point where force is applied very stable (hence safe). Made out of fine materials and built to last, it is tough enough for daily use. This product allows customers another strong advantage--a fixed object of training for home or apartment without having to repurchase over time. Moreover, the square dumbbell is anti-rolling storage because of its shape, it is also suitable for home fitness centers where space might be tight.
