I am not an expert on strengthening and conditioning, however I do know that in today's health environment, that a person who is in the hospital for more than 1 to 2 days is very sick.  Even when someone has a shoulder replacement surgery, they are only in the hospital overnight.  This was a serious health problem and you can not rely on young men who are trying to please new management, to say "I can not continue as I am hurting.,  especially, when others are looking at you with disdain [see Carrington's tweet].  It is the responsibility of the strengthening and conditioning coach to manage the training so that no one winds up in the hospital with a serious problem and possible kidney damage.  That is a sign that this coach does not understand what he is asking.
