Question about adult swim club?

Hello,

I am considering joining an adult swim club. They focus on fitness swimming, competitive swimming, etc. I was wondering if since it is an adult club, would a physical be required before I can participate? I looked on the website and it did not mention anything about it, but does that mean it will not be required at some point before I can practice? If one is required, what would be involved for an adult female? Would it just be a basic exam such as height, weight, blood pressure, etc.? Also, I don't have a primary care provider. Therefore, where can I get the exam since I am over 21 and I think Walgreens only offers this service to people 21 and under? Any advice would be greatly appreciated. Thank you.
