Ask the Trainer
Here is where you may submit a question which I will answer to the best of my ability.
I am not going to come off acting as though I have all the answers, and any trainer who says they can is greatly exaggerating. However, in our industry things which are myth and things that are known, are better asked to a trainer. Trainers do know more then your average workout buddies, mainly because who told them but another workout buddy, all who were not or are not certified. But I will give you the best answer my years of experience and what I have read from the science of sources. I will post the more interesting ones with my answer.
