Not sure why all the hate but here in Philly, the 'gay gym', 12th St. Gym, which I belong to, is one of the cleanest, friendliest, and best of all, most affordable in Center City Philly.
The gym is in the heart of the Gayborhood, but it also appeals to the large college student population here, as well as local seniors, both gay & straight.
The gym has an incredible roster of trainers, men, women, gay, straight.
Surprisingly, Philly has several other 'gay friendly' gyms in the Center City area,
but 12th st. Gym can't be beat.
Oh, and you know, gym cruising happens whether or not the gym is gay friendly.
