isnt Blackhouse in Torrence? not sure how accessible it is for a regular dude though.
I've searched everywhere for Blackhouse Torrance. I heard it's by invite only...sucks, cause the screenshots of the inside look great.
There's a gym in Hermosa (I think) called boxing works, good legit instruction there. I would go if it wasn't so far.
I go to both Boxing Works and UFC gym....PM me if u got any specific questions...both are great places.
