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

either or, all that matters is that you’re getting close to, or achieving failure. Generally, I recommend doing low-moderate reps (5-10) with heavier loads, but especially when you’re first starting, prioritize your form above all. Start lighter than you think you need to, work in the 5-10 rep range, then move up in weight as your form develops.

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