I've been lifting for a few years now, but since March, did not get stronger. In fact, I was weaker. I tried everything. I train 5 times a week, only 1-2 muscles each day and each week, I have already changed my training.

I can eat 135 grams of protein + eat 6 times a day, I even asked my local gym coach and he told me to take a couple of weeks and make great games high rep (15-20).

So I did and how it worked, but now I'm back to square one. I do not really think I'm doing something wrong, but it is obvious that I am. Please help me understand what it is.
