Originally, the kettlebell was used as a counterweight for scaling produce in Russian farmers markets. Today it is an integral part of one of the most effective, high-intensity workouts around the world. Essentially a cannonball fitted with a tea kettle-like handle, kettlebells are available in weights that range from 10 to 100 pounds. The kettlebell workout is gaining widespread popularity because it works the entire body as opposed to targeting individual muscle groups. This fact makes the workout relatively short, about 20 to 30 minutes, and amazingly effective. The results are visible almost immediately, and to progress in your workout, you need only to increase the weight of your kettlebell. Here are some of the best kettlebell workouts in Pittsburgh for anyone looking to get a jump start on physical fitness in the coming year.
