I've never thought about getting pairs of kettlebells but i have 4 at home ranging from 18, 22, 26 and 28kg, I often use these in my shoulder workouts and use them alone to work my shoulders and do alot of lunging with them, they are very versatile, often easier to use than a dumbbell for certain things because you can rest them in the palm of your hand without worry of slipping, although cleaning two together and getting tired towards the end of a set it looks like you'd have to be careful not to crunch your thumbs between the handles .. ouch. Cool thread thanks for the videos chaos!
