you bet 
when the fat covers the physique, theres not much else left to brag about than "weight lifted".
anyone whos bragging about such its 99% that they look like shit, lifted weight is so irrelevant to build up muscle, and its such a vague term, its entirely pointless to even discuss it.
let the physiques fo the talking instead.
saddest thing is, most actualy never learn, its akin to going blind through life.
here we are discussing how to warm up for lifting weight, lol, this is incredible.
20minutes warming up?what is this?planning a leave for a mars mission?
Totally agree! I can understand this whole warm-up business if your only job is to lift weights, for the sake of lifting weights (i.e. powerlifter or olympic lifter).
But I don't think there's many professional strongmen out there.
So what's with all this warm-up shit? Honestly, guys have gone to the gym for decades and built great physiques without 30 minutes facial stretching and pre-activation and foam rolling and ART and all this shit. It's just marketing bullshit to a sub-culture of a sub-culture, propagating bro science. "Oh, the reason I'm not big, is because I have imbalances preventing my t-spine from allowing me to dorsi-flex properly in a squat so as to keep my pelvis in posterior tilt". Seriously, spare me. What a load of shit for the average guy.
Just pick something up that wont crush you, lift it a bunch of times with some good form, and you're done. That's 99% of it. The rest is all bullshit.
But we lifters love to overcomplicate what should be a simple hobby.
Again, for all the athletes and what-not, sure. When I was an athlete, it mattered. I'm not anymore. Just an average guy in the gym. Not going to be in WSM, or bench in a shirt, or make the Red Sox farm team...just an average guy. So average workouts will do for me just fine.
Lots of sets, lots of reps, lots of exercises, not so much weight I can't feel the muscle for 15 reps, full ROM...don't eat too much, starve a little bit, try to eat good foods that came from the earth... It's really that simple.
