A kettlebell is a cast iron weight that looks like a cannonball with a handle. Kettlebell workouts are great because they’re efficient and build strength, stamina, and power all at the same time. If you have a kettlebell, you can use it for a quick and easy kettlebell strength workout at home. Or, use it for a kettlebell conditioning workout from home. If you’re new to kettlebells, start with my favorite kettlebell workout for beginners, the short kettlebell kicker. Or, jump right into my kettlebell workout for arms, and kettlebell workout for legs.
