Check out the H2H (Hand to Hand) series by Jeff Martone. There’s 3 dvd’s H2H 1 “Kettlebell Drills”, H2H 2 “Harder, Faster, Stronger”, and H2H “ Kettlebell Circuits”. Jeff is a well respected guy in the fitness community and both Pavel and Brett Jones endorse his work so that should tell you something. If you can only get 1 dvd I would think H2H 2 might be what you’re looking for. I’ve got the “KB Circuits” dvd and believe me these workouts will toast you along with improving your hand to hand juggling skills. You can find the dvd’s at the store on his website at TacticalAthlete.com. Also go to YouTube and do search for a video titled “Kettlebell Juggling, Jeff Martone”. He puts on a great demonstration of the kind of juggling you can expect to learn. I tried embedding it here but it’s not working for some reason.
