It’s really about just not being a hero in the gym. Doing consistent, solid workouts but nothing crazy.
IMO, the problem people have with squats is that they simply go to heavy, the result being knee and low back issues. I believe everyone would be better off if they didn’t squat with a weight that they couldn’t get onto their backs if they didn’t have a squat rack and had to start with the bar on the ground.
Interesting theory, and one I can't really argue with other than to say 2 things: I and many others would have missed out on some great personal accomplishments when we were younger. I also believe that learning how to squat heavy, and for sets of 12-20+ reps teaches a person an intensity and focus that one can't get from any other exercise. Once you've mastered pushing through that pain on squats everything else seems fairly easy to lock into.
Back in the 90's when the gym I worked at got the first power rack I'd ever seen, I started going heavy in it with no spot. I stayed pretty stagnant with my progress.
Fast forward to a year later when my training partner took me under his wing, and when it was leg day for the first time I headed to set up in the cage... he asked wtf I thought I was doing? He started wiggling the old PL squat stands into alignment, and told me to get my ass over there and do my squats right. I said "but there's nothing to catch me if I fail". He replied, "if you're afraid you're going to fail, you probably won't" Solid advice and theory. Fear is a great motivator!
I will admit that the Jay Masters thread made me use the cage, and safety bars for the first time in many many years today, and I'm doing baby weights. You're 100% right with what you're saying for guys my age, but I have it in my head that I want to get back to 315 for reps for another stretch before admitting age has defeated me. With what I've done in the past, I feel I should be pretty safe if I take it super slow. (knock on wood)
