The Kosher Gym.

get your all-beef beefcakes! fresh, hot, and overseen by a rabbi.

yum.

Separate areas for men and women to exercise. As Orthodox Jewish women dress normally modestly a separate facility would allow them to work out without fear of being seen by the men while “not fully dressed”. Most religious areas have separate swim hours too.

As a frequent gym goer in my college days, I clearly remember the guys leering at the girls in sports bras jogging, using the thigh-master, etc, hehe. I guess there is also benefit to the guy who wants to work out without that kind of distraction.
