first off i did search before asking this.. out of 34 hits none answered this question...
is negatives a good form of training for bench. as in a every once in a while method.. i hear alot people say use it on your lite days, then people say that doing to many or negatives at the wrong time might be over training your CNS..
so if negatives are good, what percent of your max? how often? and how should they be used? .... or not at all?
