I really enjoy swimming!  I especially love doing laps in the pool for exercise!  Do you enjoy it?

Me too! I really enjoy recreation, exercise, and sport swimming! How often do you swim?

I try to swim a couple days a week, especially when it is hot like it is here in Florida.

Good idea! It's a nice low impact alternative to activities like running!

I agree!  My knees are pretty bad from running for years!  What is a good distance you think I should swim for?
1_Wizard
Any amount is good to start! As humans, holding your breath underwater I think is most important!

I agree!  Is it hard for little kids to learn how to swim?

Well humans can undertake rudimentary swimming within weeks of birth! Pretty incredible!
