In any change situation there is going to be better results if there is reliable, valid and timely evidence and feedback. And who has access to that can make a profound difference.
Brisbane has long history of producing world champion swimmers (Leisel Jones, Keiren Perkins, Hayley Lewis) and many more have trained here. I’m not one of them. I’ve been encouraged and given feedback as I happily churned out a few laps at the University of Queensland pool or perhaps the Centenary Pool. Keep my head down, lengthen my stoke, reach out more, keep my hips higher, increase my kick rate and breath both sides. I worked at everything I was told and there was almost no improvement in my results. I thought doing it harder and getting stronger would help. It didn’t, at least not much! Then something important happened.
