I would just recommend that you avoid using chains and especially bands on dynamic effort day until you have a solid base of training. They can put alot of stress on your CNS and joints. Dave Tate says in his "Accomadating Restistance" article (http://www.testosterone.net/html/body_127resist.html):
Training with chains and bands can almost be thought of as a form of eccentric overloading. This type of training should only be used by those with a strong training background. At least three yeas of consistent training or a "class one" in the sport of powerlifting. If you're not at or above this level then general strength training should be enough. This style of training can and will make you very sore.
IMO, three years of training isn't required, but at least several months of straight weight should be used before introducing the dynamic resistance.
