[quote="beforewisdom"]I can never do a progressive resistance program without using up at least an hour by the time warmups and other gym things are rolled in.
There's some witty quip by Rippetoe in his book about lifters claiming to not have time to train that would be apropos here...
That being said, with warm-ups, training, warm-down and transit time, when you get in the 3:00+ range it can get kind of frustrating. To that extent, Stronglifts is probably the worst offender for long training sessions of all the "major" progressive loading routines out there.
There are quicker (and IMO, better) routines designed by better qualified people, that don't come with a massive cult/really creepy thoughts on politics, society and gender/questionable training recommendations in tow.
