I hope you don’t mind if I share a personal story?
My teenage years were spent in Germany and Germany, I might add, has the best indoor and outdoor pools in the world. While in high school there in the 1980’s, every Friday, our last two periods were devoted to mandatory swimming where the instructor would teach us proper swimming techniques the first hour and allow for a free play after that. My passion for swimming was born and I have not stopped swimming since. I love it! Like you said, swimming is not just about cardio but also about strength training & has many, many cognitive benefits, too. I swim 4 times a week- 45 -60 minutes.
