I don't know of any free info, but you can view video clips of some cb exercises on www.circularstrength.com
- look under Olympic Clubbell Sport on the main page to see clips of swipes and mills. Also click on the Free CST magazine on the main page and go to the current issue and check out Miracle Round (anything by Max Andranov is amazing). Another site to view cool stuff by Max is www.clubbelltrainer.com
- click on Max's Page to see some great clubbell combination/catch moves.
