Hi, Ya'll.  First post here.
  Just wanted to mention this to folks.  http://www.youtube.com/watch?v=TjIpg1h2j2s
  I've being doing indian clubs for a little bit, mostly coming out of trying to find a way to deal with my shoulders and wrists getting jerked around in aikido.  That said, I've noticed a few "slingers shoulder" related posts on here, and thought I'd post something about this.
  The transfer between indian clubs and slinging strength/stability seems really high... in fact one of the exercises virtually IS the arm motion for a figure eight throw. 
  Anyhow... it's a weight you can hold in your hand and safely swing... usually between 1 and 5 pounds.  There is a heavy version of these clubs that are handled differently, that were the original form of club ex (these lighter clubs are actually an english misunderstanding of an indian exercise that became its own discipline.)  I have carved some clubs before, but you can do a lot of this with a milk jug with water in it. 
  anyhow... there you go!  Hi.

Looks interesting. When I first read this I thought, this guys trying to sell us something by making it seem sling related! But looking at the video I think I was wrong, these may be perfect for preventing slingers elbow when combined with a warm-up before slinging. Anyone who wants more info on Indian clubs can go to wikipedia. Thanks for the info!

Geez... who'd have figured slingers for such a guarded and suspicious bunch! 
  I will sell you that $20 milk jug with water in it, if you're interested. 
 
  In all seriousness, though, these things come from an older practice of swinging heavy clubs by indian wrestlers http://www.youtube.com/watch?v=6FdZuzY0n1M , which in turn comes from... well... using a club as a weapon!  so there's actually a bit of interest there, eh?  Try it!  It's addictive!
  Anyhow, it's a bummer that a lot of physical things don't come with "how to keep it from tearing up your body" instructions.
  Have fun.

Welcome to slinging.org, Drewbearsmth;
     I've never used Indian Clubs, but my dad used to swear by them.  I can see where they'd be perfect for conditioning for slinging.  Thanks for a good tip.  We do get a lot of spam here BTW.

I've got two sets. One pair are made from white oak and weigh 2lbs (http://www.revolutionclubs.net/) , the other pair are steel and weigh 3kgs (ca. 6lbs). I use the lighter ones for the more "twiddly" exercises where my wrists are not so overloaded. The steel ones are better for slow exercises and make a good substitute for a two-handed sword. I'll try to bang together a video of some of the training exercises and how they pertain to sword training.

The funny thing is club swinging used to be an Olympic event!
