Don't be afraid to test your limits at the gym, but remember to be reasonable about it. You don't go over and throw an extra 100 lbs on your bench press without a spotter, unless breathing isn't all that important to you. Same goes for a squat rack unless you hate that whole "standing upright without pain" thing that all the cool kids are doing. I'd be lying if I didn't get a good laugh now and then from someone who grabbed dumbbells that were at least 20 lbs out of their class and dropped one on their foot either. In any regard, don't show off, be responsible with your own body, AND test your limits if you want to get gains and not losses.
