I知 moving to LA. What areas do you recommend?

What I知 looking for, in no particular order:

-Relatively close to night clubs and other target rich cold approach opportunities.
-At least average female to male ratio in the area.
-Good number of singles in their mid 20s to mid 30s.
-Friendly people.
-Weight gyms that are open late.
-Recreational opportunities/outdoor activities
-Not a high crime rate area.

Thanks for your suggestions.
