I do, 5 AM daily these days during the week. Same gym that walterwhite used to go to. Its a good place, with only a few tool-bags there.
I use mine for the random weekend workout, or if I dont feel like going to the gym that day. My wife trains w/ me, and she prefers the commercial gym, so...
My gripe with hhf is the hours. Summer hour changes and not open 24/7 and on holidays (I live a boring life

).
Nice garage gym!
