Lifetime fitness does not offer a cold plunge to the women at lifetime fitness, however, the men do have access to this amenity. Women must pay the same fees, so we should have access to equal amenities as well.
Twin Cities cold thermogenesis was started by a group of women where they swim three times a week in the middle of winter in Cedar Lake located in Minneapolis, MN. Men were allowed to join us but the group is still 70% female. Women see the benefits of cold plunge and would like to have access to such an amenity if the men are able to do this.
If this doesn't work you're welcome to join me in pursuing legal action: Minn. Statute 363A.11, subdiv. 1(a) Full and equal enjoyment of public accommodations: “It is an unfair discriminatory practice: (1) to deny any person the full and equal enjoyment of ... facilities ... and accommodations of a place of public accommodation because of race ... sex”.
