Depends on what part of S. Cal you are going to. If you are going to be anywhere near Venice, then you have to go to Gold's in Venice. It is the best gym anywhere.
If you are going to be a little closer to Orange County or San Diego, try Powerhouse gym in Fullerton
i will definitely hit muscle beach/golds...just wondering if there are any other in that area. i used to live in OC-mission viejo. so i am not too familiar with venice area except for golds.
Dude you have to go to muscle beach and get in the cage. The greatest feeling to go and lift while people are looking, and taking pictures of you.......damn that was a rush. Golds is the place to go in getting away from the littles....
