You can have a private club with gym equipment that is exclusively for men. But when you're a business open to the public you cannot discriminate based on certain characteristics. Bob's Burgers can't sell just to men. But Bob's Boys Club that happens to have a kitchen which sells burgers to its "private" membership can absolutely keep women out.

You can if those certain characteristics are currently in favor.

Plenty of women only gyms exist

Bonafide clubs can discriminate against anything, including protected classes. Might not be a good look, PR-wise, but it's been confirmed in court cases.
