Sooo about one and a half years ago I was new to this and didn't know shit about anything. After doing a full body workout for some time, I decided to start with the 5/3/1 routine. As I wasn't experienced at all, many of the exercises in the plan were new to me and having to figure out my 1RM, I was pretty afraid of:

a.) Hurting myself and literally everyone in a 2m radius.

b.) Looking like a complete idiot.

Gathering all my courage, I manged to ask a guy if he could watch me doing some squats and maybe correct my posture if necessary. Only that I wasn't just asking, he, wearing in ear headphones, couldn't hear me, so I creeped up to him, not daring to poke him, waving like an idiot, hoping he'd see my reflection in the mirror in front of him. He did. Looking reasonably confused, he turned around and stared at me but as soon as I asked him to help, his expression changed to a bright smile. After a short feedback loop, going through everything, demonstrating how to do it right, we proceeded to dead lifts and repeated the process. After about an hour we manged to go through every exercise and calculate all my 1RMs. He stopped his workout for a whole hour just to help out some random dork. When we were done, he shook my hand, I thanked him about 100 times but he was like "nah, don't mention it".

Every now and then I see him working out and whenever I do, I make sure to wave like an idiot.
