I own a red Combat Sports International Grappling Dummy. I think it is a very dangerous piece of training equipment. It's so overfilled that it might as well be made out of wood or cement. Does anyone know if these dummies break in? What do you recommend doing to break them in? Sludge Hammers? jk But seriously, the chest of the dummy is so over-stuffed that you feel like you're mounted on a horse when you're in mount position. Combine that problem with the arms being pretty short, and it makes it very difficult to go for armbars from the top. I also own their Muay Thai grappling dummy and it is great. It's not filled as much and it seems like it's breaking in with out the use of a tractor rolling over it. Does anyone have any experience with these wooden-like grappling dummies? Edited: to avoid anything misleading Edited: again because... because I want some advice and I'm tired of hearing about the title of this thread. Man this thread fails. I take full responsibility.
