Recently joined the YMCA and this is my "home" ymca. I LOVE the equipment and 'most' of the staff. I have hit the gym (been a member about 30 days) at very varied times but have settled on 5 am for strength training (mon/wed/fri) and 3pm (ish) for cardio (Tues/Thurs/Sat). At either time it isn't overwhelmingly crowded.
I will say at 5 am (and I assume other times) there are plenty of meat heads in the weight room - grunting, slamming weights, flexing in the mirror. I also find it entertaining to see the fashion show that occurs in the weight room (I like to ppl watch between sets). I have NEVER seen so many coordinated work clothes in my entire life. Matching shows, pants/shorts/shirts and often times hats. None of this bothers me, it is just entertaining.
I have not met anyone very friendly there and I assume that is because it is the "SoPark" area - but since I don't go to the gym to socialize I guess it doesn't matter.
