yikes shame they'd do that. I'd kill to have some one show my stuff like that. i tried gaining last year, i didn't commit to going to the gym because i had no clue where to start and how to do them safely, so i only gained a little bit then i got fell ill and got too lazy to get back into it. now I'm trying to relearn everything and steadily get my weight back up (180 cm, 53kg right now). thank goodness for online resources and communities to ask around for info.
