Our Clients Say

“Just a quick note to say thanks for the session yesterday. I've read a lot of the Swim Smooth book and Web based material and it has always seemed good, but really came to life yesterday in the presentations, analysis, drills and chat. That's the measure of a great coach. ” Mike Higgins

“I compared the video to an analysis I had done two years ago and am glad to see improvement! Off tonight to practice some more but be assured that I am feeling the difference already! The bottom tiles of the pool have never been so interesting!! ”Angela Ward

“Thanks for the session on Saturday we both really enjoyed it! We managed to get a swim in this morning together and worked on the skull one and two and bubble/breathe! ”Julie Riches

“Thanks very much for providing the swim video analysis last weekend. It was all really useful and I keep going back to the video to improve my visualisation of what I am doing wrong and how I should be doing it. It's really got me back into my swimming as I've got something(s) to focus on. I have been swimming several times since and while I wouldn't exactly say I'm replicating the strokes of those professional swimmers you showed in the video(!), I'm already recognising how much less drag I feel when I put the things you mentioned into practice. ” Andy Pugh
