You need to train arms like you train legs, chest, and back. Do not treat that shit like it’s an “accessory lift” because they’re all lifts and you have to go hard enough to the point where your neck veins pop out. In terms of weight and reps, do 2/3 sets at a weight where you’ll fail between 8-15. Eating extremely high protein everyday is vital.

start off with arms in your session go heavy if your form is good aim for 4-6 reps but you’re a noob so go for 8-12

I’ve heard a lot of mixed things but think you wanna do roughly 70% of your max for 8-12 for “optimal” growth
