Questions about lifting during SPP

At a certain point you will see and understand that everyone wants to comment when someone appears to be doing something. Note how few people you see out there in general terms and notice how organized they are not?
People mean well or sometimes they don’t mean anything at all because they do not know anything. I don’t know who this person is or what qualifies them to say such a thing and what is too much work and for whom? IF someone is used to doing something and has successfully been doing something with a proper progression that makes it entirely different than an average person who has not been doing much of anything.
