I am doing althernative days training I mean one day Chest/Arms/Abs the other day Back/Shoulders/Legs
I know rest is important for muscle growth
So If I trained my chest/Arms/Abs on Monday idially the muscles will have 48 hours rest till the next exercise time
But actually when I train my back the Biceps get used as well Like when I do Lats Pulldowns, I fell Biceps are fatigue a little too
So Should this be consider as rest time as muscle get trained lightly
or by rest we me dont use this muscle as much as possible?
