Vegan, what do you consider maxing out? Are you referring to a one set max?
I'm referring more to 1 rep maxes, something that tends to get the best of a lot of guys who are after top strength and are always wanting to test themselves. As I've found as I get closer to 40, I can't max out as often as I used to without it taking a heavy toll on my body, but 10 years ago, it was no problem to shoot for a new PR on a lift every few weeks.
After being exposed to more powerlifters this past few years, I see how many of them only max out in competition with very, very few attempts done in the gym for 100% on a set. Lots of guys will make projections for their max in a lift and only try to hit or exceed it in a contest, whereas in some gyms you can find guys trying to set a record every time they walk through the door. Slow and steady without beating yourself into the ground is the best approach for longetivity, the guys who aren't cautious are usually the ones who are out of the iron game by their early 30s and have nothing but "glory days" stories left from there on out!
