BigMike,

Yaish definately gave great instructions on those chain weights. I have a se that I made. Compared to the "pipe" model that Ryan and I show above--the chain weight slop around a bit more. That's ok if you are experienced and your footwork is good, I think it even adds to your practice because the weight 'fights' ya a bit. But if your footwork isn't spot on, it can be more work then necessary and actually NOT allow you to practice good form--Ok just my opinion I only weigh 185 lbs--so for a 'workout' I use the chains--for form I use the pipes.
