Almost 75% of your musculature is located in your lower body and your back.
Rest is present in your shoulders and chest.
And finally, your arm muscle (which comprises of no more than 5% of total musculature; honestly I don’t know the exact % but it not be more than 5%)
So ask yourself this question:
If I do barbell curls, or concentration curls everyday, will I build muscle faster?
I am sure you know the answer by now.
If you want to build muscle overall, then you need to train the biggest muscles in your body in the following priority:
Back: Deadlifts, Pullups, Lat pulldown
Shoulders and Chest: Military press, bench press
Arms: barbell curls, triceps pushdown
Give priority to the muscle groups as given above and thats the fastest way I know how to build muscle.
