For me it would be that lifting can take time. It's okay to start with light weights and it's okay that getting bigger will take more than three months. Sure, pushing yourself is good to make progress, but everyone has their limits.
Also, lifting can be for more than just getting bigger. In the beginning I was hyper focussed on getting more muscular and it led to me taking awful homemade protein/caloric shakes which cannot be healthy long term. It took me pretty long to understand that this way of training was not what I wanted. Luckily I now know that I want to focus on strength and stamina and that size comes second.
How about you?
Wow, youtube told me I'm wrong?! Well that settles it then. I'll be sure to go tell every athlete, coach, and professional I've ever worked with that they're wrong too! In the future I'll be sure to cross reference my medical advice with social media, that was my bad. Thank you invent_the_future for your great insight, God Bless.
Check this out, this guy really shows you how to do it! https://yewtu.be/watch?v=vPPk0QqQW4k
Jokes aside, don't get your medical advice from grifters or strangers on the internet kids. That includes me, I was just using my case as an example. Point is to go ask a few professionals IRL that do this for a living how to do whatever it is you're doing, then cross-reference the information.
not saying to get advice from the internet, just sharing a readily-available source that's quite reliable and is consistent with precisely the advice I've personally received from professionals IRL
the guy himself is a physical therapist but whatever, be as condescending as you want to be
From what I've been told that method will at best work out the wrong muscles, and at worst cause serious injuries like hip damage or blowing out your knee. Like you can go lower than 90 degrees, but going too low will cause issues. Same with the feet angle/width thing, sure you can get away with it for awhile, but over time you can cause strain and damage. Maybe I'm wrong though, maybe I really have just been talking to the wrong people. There's a wide range of opinions on this stuff, so the best you can do is talk to a wide variety of people and try to come up with a consensus the best you can.
