Does it get easier after a few minutes in? I swim ( a lot) and each day the first 10 minutes are horrendous. After that everything seems to calm down and adjust and I manage my 40 lengths just fine. Its the same when walking the first 5-10 minutes I am a wheezing mess but if I persist then it generally gets easier? Anyone find the same? Or is it me being a bit weird?
Just to let you know that nothing got easier in the photo below - after 5, 10, 15 , 45 minutes I was done in!
