I have two practical questions concerning Modesty (Tzniut) for men and what Halacha says about it which concerns bodybuilding:
Can a man take half-naked pictures of himself (with only shorts or pans on like all bodybuilders do)? If yes, can he post those pictures?
What can be Judaism's view on bodybuilding, in general? I suppose it may be negative comparing it to idolatry (obsession with one's body) and cultures of Romans and Greeks.
