QTDDTOTT:

How heavy is the standard shrug bar?
20kg?
The one in my gym is a proper pain in the arse to unrack, definitely feels heavier than 20 desu but maybe I'm wrong

So it seems my joints/tendons/ligaments are fragile as fuck. Since I started lifting 1.5 year ago I have already had problems with my wrists, shoulders and knees (I am fucking 20 yo). Talking about pain, clicking and other shit lasting for like a few months, in each area. Because of this I did progress that normal guy could do in two months of serious lifting.
I'm also not that type of guy who tries to squat 2pl8 on his first training, I'm very careful about form and not pushing too hard. I also always warm up well and stretch after training.
At the moment I'm not even lifting because of all this. Can't squat because of knees, can't OHP/BP because of shoulder.

So is there anything I can do to become more injury-proof? Is this shitty genes or maybe some illness? Should I consider taking joint supplements or it's a waste of money?

You might have lost muscle mass, but the structural, CNS and metabolic adaptions stick around for the rest of your life. So yeah, you'll gain pretty quickly.

It's a meme that mostly helps people who snack too much.

The soreness could be just DOMS in your mid/lower-trapezius. As long as your spine dosen't hurt you're probably fine.

Yes. Donkey kick machines also help quite a bit.

Take the bar to the scale. Weigh youself withouth and with bar. Mystery solved. (The formula is: mass of yourself with bar - mass of yourself = mass of bar.)

Why is it ok to ohp in the squat rack but not curl?

I'm kind of like this as well; you might have bad form.

Don't stretch before/after working out(stretch at a set time every day instead), warm-up well, and make sure your form is good.

If you already do all the above and you're 100% sure your form is good, I'd suggest taking supplements and/or start using machines instead of free weights.

After I fixed my form and worked on mobility everyday, all of my pain/clicking/tendon snapping shit stopped. It was bad because I injured quite a bit of my body with shit form lifting as a teenager and all of it came with me when I started lifting again as an adult... had to strengthen everything and be autistic about form.

The weighing scales in my gym costs 3 quid to use lmao

How to achieve Hercules mode? I think it's the perfect physique.

I'm currently cutting at 1800 calories a day but I have spent the past 3 days eating nothing but pizza and drinking beer. Should I just kill myself? How bad will the damage be?

sunk costs. don't worry about it and get back on your diet.

Are you a woman? Just create a makeshift scale out of gym equipment - you've got all the weights you need, for starters.

Because lots of people don't know how to clean the bar, and even if you do - beginners run into problems with core tightness. Curling can be done on half the machines (even the leg ones) and with every dumbbell without taking up the rack.

Get back on the train. Most people are fat by because of the "I screwed up, might as well go all in" maxim, hell, it's the reason for half the ills in this world.
