You can avoid being stuck on the bench by learning how to gauge whether or not your next rep will go. This requires that you be conservative but observant. BUT, if you train by yourself and there is the slightest danger that you could get stuck, NEVER COLLAR THE BAR. This way you can always dump one side off and get it off of you before the darkness closes in for the last time. This is very important: the bench press is where virtually all of the fatalities associated with weight room activity occur, usually guys training alone that get a crush injury or suffocation. So,TAKE THE COLLARS OFF THE BAR IF THERE'S ANY DANGER AT ALL OF GETTING STUCK UNDER THE BENCH PRESS.
