You guys have witnessed much more impressive feats of strength than I have. I guess I've only ever been in one serious strength gym, though.
I had a friend I'd train with who was juiced up, looked incredible, and could do a few reps with 200kg (440 lbs?). That was mind-blowing to me. I hated spotting him as I was pretty sure I would be useless if something went wrong.
Another mate was really short (approx. 5'5") but he was insanely well-built and had one of the best physiques I'd ever seen in person. He claimed natural to others but he told me he'd 'experimented' with Dianabol and test. I saw him rep 140kg for 6-8 reps a few times, and that was impressive as hell. He also had great cardio and was a reasonable boxer.
*Forgot to mention I was talking about bench press. What a retard.
