Oh jesus, yes strength is important to build up right now, but that doesn't mean things are going to go swimmingly if you shut your eyes to things like proper diet, mind-muscle connection, and pushing the limits of recovery the way I think every novice should be doing.
"Stop worrying about bulking and cutting"? You do realize the whole meaning of "bulking" is to eat enough protein and calories to build muscle and strength?
You are 150LBS. That isn't "skinny fat" just because you don't have a 6 pack. THAT IS JUST CALLED SKINNY. I am not suggesting you start eating a chocolate cake every day, but yes bulking is something you need to be "worrying" about if you want to be good at this at all.
Let's take a few scenarios shall we...
SkinnyguyA doesn't worry about bulking/cutting and just lifts 4 days a week worrying only about increasing his "compound" movements. After 9 months, he's gained 10lbs of bodyweight, and subsequently only gained 25lbs on his squat/bench/dead. No one can tell that he looks any different except maybe his mom.
SkinnyguyB shovels in the calories and protein like it's his job, lifts 6 days a week trying to increase every basic bodybuilding exercise (both big and small), and after 9 months he has gained 45lbs of bodyweight, added 100lbs to his squat/bench/dead, and is significantly more muscular in spite of also being fatter.
SkinnguyC shovels in the protein like it's his job, but consistently avoids sugar and any foods that are conducive to fat gain in spite of eating plenty of calories, lifts 6 days a week trying to increase every basic bodybuilding exercise, and after 9 months he has gained 20lbs of bodyweight with no increase in bodyfat percentage, and has added 75lbs to his squat/bench/dead. He looks both leaner and more muscular than the other two.
Which Skinnyguy do you want to be?
