Hmmm... here are a few
"You're going to hurt yourself lifting that heavy all the time"... this was said just after doing a warm up set.
"You can tell which guys in here use steroids... they all have tiny legs... I can tell you are natual because your legs are big too."
"You can curl alot more weight if you kinda swing your body with the bar and lean back at the top"
"If I do my dumbell kickbacks like this, it saves time on my workouts, because I can work both my triceps and my biceps on each rep."
"Boucing the bar off your chest makes you alot stronger on the bench."
"If I do all of my laterals with cables, it really ripps up my shoulders... I mean looks at the cuts!"
"No, you have to do all your reps as fast as you can to get big" as I watch in amazment as he did alternating dumbell curls with horible form at a speed of around 3 reps per second with 5 ibs dumbells.
And my favorite:
"Man I get the best burn in my biceps when I do my curls on the leg curl machine!"
