Kettlebells are compact, inexpensive, virtually indestructible, and can be used anywhere. The unique nature of kettlebell lifts provides a powerful training effect with a relatively light weight, and you can replace an entire gym with a couple of kettlebells. Dan John, Master SFG[1] and a highly accomplished power athlete, famously quipped, “With this kettlebell in my bedroom I can prepare myself for the Nationals.”
