question regarding muscle gain

hey in kelly b’s bible he says training with 4-8 reps and lifting heavy will result in better muscle gains…well for my program i lift for 10 reps on upperbody since its my hypertrophy phase and ill be doin that for like 2-3 weeks…is that still ok will i gain muscle while eatin right?

Without knowing the specifics… (what you are actually doing, and the total volume sets and reps) we cant give you a complete answer. Generally in that rep range if all else was on point and you were eating enough you should gain at least some muscle.
