On GoSwim I saw a demonstration of how he suggests coming off the wall on a turn. The demonstrator had his head well below his arms which were held together as tight as possible. To me this seems to be not as streamlined as having your arms held as tight as possible against your ears. Not as he was doing with his head below his arms.
Fortunately I am flexible enough that I can achieve this position but question it's advisability.
Would like to hear what the forum particants have to say about this.
May we swim with ease at the speeds we choose.
