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?
Exactly, you can jack yourself up really bad quickly by doing the wrong thing. Especially when it comes to things like squats. It doesn’t hurt to ask a reputable source (COUGH not youtube COUGH) to figure out if you’re doing it right. It’ll save your body and give you a better workout in the end.
