Ur schedule must be on Monday n Thursday chest, biceps n forearm on Tuesday n Friday, back traps n triceps on Wednesday n Saturday shoulder n leg Sunday is for resting don't try the push pull leg bcz on push day u might not feel ur triceps or shoulder so try the one which I recommended u n also don't work out any muscle outside of the schedule even if u skip a day just stick to the schedule otherwise u will not see any changes like if u see the schedule which I recommended for u there is a 2day gap/rest between the same muscles which u trained n muscles need to rest inorder for them to grow otherwise mnm aynet lewt atayem if u constantly hit biceps n chest every day, u must work legs I know that it's mentally challenging n all but if u do that u will change ur upper body fast bcz if u work legs it will give u a testosterone boost hence fast change in overall upper body do triceps bcz they r 70% of ur arms if u want bigger arms do triceps n also don't forget to train ur forearm bcz they will improve ur grip like if u train ur forearm more u can grip the weights i.e the barbell or dumbbell or machine handles easily n they won't slip out of ur hand n also when u do chest presses, shoulder presses n lateral raises tuck ur elbows at least 30-45⁰ degrees bcz on chest it would shift the tension from the shoulder to the chest on shoulder risk of injury would be reduced on lateral raises u will be able to hit the middle delts more....now inorder for u to change diet is the main thing if u have a proper diet u can get big fast sooooo for ur diet if u r gonna cut it must be protein focused diet if u r gonna bulk it needs to be protein n carbohydrate (sometimes fat but u might lose it) based diet but in ur case u must first bulk i.e get big/fat wiz muscles then cut if u do this u will get big n also have more muscle sooooo for u to get bulk u must drink beso, banana, milk n oats(aja) shake it will boost ur weight(u must drink this like 6x per week after ur workout) then u must eat banana, avocado, meat, fish yogurt etc but if u workout on an empty stomach(bebado hod/lerebek sil)ur body is gonna digest or use up the food which it stored but if u workout on a stomach which have food(if u ate food before 30min)ur body is gonna digest that sooooo before going to the gym eat something like 30min seqerw gym bet letehed setel malet nw n the last thing is consistency I know u might not notice some changes in the first weeks or months but u will see some changes in strength mnamn after 2month of working out u will be some physical changes n u might pick up some heavyweights if u need some more tips on how to change I can recommend u some Instagram pages that can help u change....yeqnak brother n continue the grind💪
