There is a fitness center attached to the hospital. You can get a gym membership without being associated with the hospital.

I've explained it to people and they look at me like I'm crazy 🤣

They changed the name since I've been there! https://www.crozerhealth.org/locations/practices/p/primary-care-at-the-healthplex-pavilion/

Best part, everything is right next to each other. Super easy to go from sauna, shower, hot tub, cold tub, repeat.

After living in Korea, the Healthplex at Springfield (Delco) hospital has the closest thing to a Jimjilbong (Spa) I could find. They have dry and steam saunas, hot tub right next to a cold plunge, and plenty of shower space. Haven't found anything comparable.
