In my experience the only thing that makes you fitter for swimming is by swimming..: there seems to be no short cut. Trust me, I’m looking!!
That said, having started ashtanga yoga (mostly hot) I’m noticing a dramatic difference in strength and also confidence
My mind set is changing, people are being very kind and believing in me, and I’m gradually beginning to believe them and therefore myself
I have watched Sink or Swim too, and omg I am in utter awe! I’m a swimmer, have done Henley mike twice, lakes, rivers, and lots and lots of lovely warm sea swims.
I loathe murky water, it terrifies me, and having only learned to swim a few years ago and worked like a maniac to get to this stage I really struggle with water outdoor. Unless it’s clear and I can see where I’m going. As a mild agoraphobic I know panic well. Sadly. I know how it stops you from doing things you should be able to.
Those amazing athletes are doing something this big and they aren’t even good at pool swimming let alone in the flaming sea or channel! Their stories are so moving, their journeys are all so emotional
I spend each programme sniffing and dabbing my eyes for them, because I know exactly how they feel!
