The Kettlebell is a cast iron weight that looks like a flat-bottomed cannon ball with a handle.
Virtually unheard of in the West, Kettlebells have been popular for centuries in Eastern Europe. They were also extremely popular with early American and European bodybuilders and strongmen at the dawn of the 20th century.
Behind the former iron curtain, Kettlebell lifting developed into a closely followed sport with local, national and world championships.
Surprisingly, Kettlebell training is now catching on as the hottest new trend in American fitness with a mainstream appeal for all fitness levels, ages and genders.
Why So Popular Now?
The reason — Core Training.
Through the early nineties American weight training focused on targeting the individual muscle groups with pure isolation. By the mid-nineties that philosophy gave way to functional training.
Functional training promotes the concept that muscles should be worked in unison, creating a healthy, functional strength that better prepares the body for everyday activities including lifting babies, carrying heavy backpacks or grocery bags, pushing disabled vehicles, etc.
Kettlebell Training is the ultimate in functional core training.
