can someone tell me proper gym routine for someone skinny like me? i weight 58kg and 174cm.
my plan is to build lean muscle..

i made some research about workout plan but there's too many of them and i dunno if it suits me or not.

for example i made a research about chest workout but there is too many of them and i didn't know which of them do i have to do.

i plan to start workout next week, and i currently planning for my schedule. my current plan schedule is :
monday: chest
tuesday: back
wednesday: leg
thursday: shoulder
friday: arm
weekend: off

can someone help me with my schedule?
