Welcome to the forum!
Great to have you here.
Cool there is a reference to No Meat Athlete here. I'm at the creator of No Meat Athlete's house right now
Anyway, a lot of us struggle with building muscle and reaching goals in general. We have to really evaluate what we're doing, take detailed notes, makes changes and observe results.
Heavy compound lifts, quality foods and consistency should yield positive results.
Have fun with training too. That's a huge part of it. Enjoy it, work hard, set goals and go out there and achieve them.
