Don't be afraid of the weights.
If this means slapping 10 more lbs on the bar or doing a triple vs a double vs a single, do it. If you look around the typical gym, the average gym goer is afraid of a heavy barbell. They won't squat heavy because they don't want to hurt their knees, they don't bench heavy because they don't want to get stuck, they don't deadlift heavy becasue they are afraid of their back getting torqued.
Take the average powerlifter, we all like the heavy weights, but even then, we are afriad of them to a degree.... I saw it myself with my hernia surgery last year. It took me months to get over that mental block of blowing out the hernia again. Once I did, I started racking up new PR's one after the other. Your brain is the single most powerful lifting aid you've got. Don't shortchange yourself by being afraid of the weights.
