Hi there, I have recently taken up swimming as a hobby - do you like to swim? 
I love to swim, I like it as a recreation although it can also be a sport, or even survival. I'ts nice for exercise too.
My personal favourite stroke is forward stroke, I find this the best for giving me a complete workout! Which stroke do you like the best? 
I think it's my favorite one too actually. All that matters in swimming is coordinated movements of the whole body and the limbs.
