Welcome to snapcity my friend, enjoy your visit--don't worry, there's still plenty of space for other coping gymcells.
No doubt you were doing limit sets of low reps week in, week out and are surprised that you ended up at your current destination. See, what they didn't tell you was that any lifter past the noob stage who knows what he's doing is leaving 2-3 clean reps minimum in the tank at all times, and is cycling his training poundages so that he is only lifting heavy a few weeks of the year. And even then, injuries are common place. And as a natty, your only chance of lifting half-decent weights is by fat-fucking yourself through forced overeating--all so you can brag on forums 'I could lift weight X on exercise Y before my back, shoulders, and knees gave out.'
