I don’t know what the best advice I’ve ever gotten is. I’ll think about it.
THE WORST:
Being told not to do things.
Don’t run! You’ll lose muscle. Well, I was running miles daily at one point in my life and was in amazing shape. When I stopped, I got out of shape. (Other options besides running, I know.)
Don’t train abs! Squats and deadlifts will take care of that. Well, I used to and had strong, somewhat visible abs. When I stopped, they got weak and went away.
Don’t train arms! Benching and rowing will take care of that. Nope.
Don’t go high rep! Low reps are the best (I was influenced by Rippetoe here). I’m not using barbells right now, but when I begin again, I’m thinking about sticking in the 6-12 rep range for a while.
Don’t squat if you have any buttwink! Believing this just led to me trying fifty thousand different ankle mobility moves that led nowhere. I don’t even know why I cared. I wasn’t worried about getting hurt, I just thought my squat needed to look a certain way. I do think a certain amount of rounding on the squat can lead to some issues, and that some people could stand to fix a few things, but it’s not the end of the world. This kneesovertoes guy seems to have better advice here than most. If I had to try to fix buttwink ever, I’d probably go his route.
I’m sure there’s more but I can’t think of it. The whole keeping your pushes and pulls within the right ratio thing has been touched on, but I fell for that too. Like Pwn said, how do you even calculate that?
Lesson: do it all. Work all the muscles, in all the rep ranges, and do a variety of activities - lifting, calisthenics, running, biking, playing sports.
I still find myself reading articles on nutrition and getting worried about what I’m doing, haha. Working on that. No longer care much about what people say about lifting.
