Do not join a gym, do not listen to any kind of trainer as they re all bullshitting narcistic assholes afraid you might look better, bigger than them, 99% of them are insecure egocentrical shallow liars, losers, who have nothing else in life other than their needles and weights.
Do not buy any kind of "supplement", any kind of magazine.
Do not waste your time training bodyparts nobody can see as most people will think you re a reincarnation of arnold s as long as you have big biceps and chest.
Do not become a "bodybuilder", lift and eat for health , family, to be a good example for kids, inspire people and let them come to you for advices without thinking you re "better" than them cause you have some muscles - remember there s always a bigger fish in the pond.
Muscles are 0.0000000000000000000000 001 of what life is about. Only losers think they are 99.9% of it.
