My mate who I am training could barely bench the bar when he started. He's doing 5 X 5 and after 2 months is approaching the 60kg mark.
Now for those who have worked out for years and know these are minimal numbers, big deal but for a bloke who has never touched a weight in his life, is basically a stick, when he sees progress and is having fun, I don't think he really cares too much about when to push pull etc. He's having fun, he's making progress and wants to keep going to reach higher numbers. When he's all maxed out he'll jump on here too and complain about what a crap program SS or 5x5 are, but at the moment, he's gone from a skinny lazy fella to actually doing something he is enjoying and that's the main thing. He's been introduced to the world of strength training and is having fun.
