Been years since I exercised regularly. Now that I'm older, I can't get away with bad form without really feeling it later. Learnt mostly by myself and from youtube. A little while ago I was complimented on my form while squatting, and today I figured out what was wrong with my shoulder (nerve impingement from an unstable rotator cuff) and now I know what to do, day 1 and it already helped immensely.
Though I guess the real win here is that I'm going to the gym regularly. Tried many times before but I always ended up quitting. It was probably the depression doing me in. Guys, therapy works, no cap.
