OK, another 'sinker' here, and I have a question for all the swimmers...
In this video (at 1:05), see how the swimmer can float (prone) and keep legs up?
or here (at 0:41)
There was another one but I can't find it now.
I have tried and tried and I cannot do this. Legs sink. There is no amount of arching back, moving arms down or up, or moving head down, for me to achieve this. The coaches seem to suggest that everyone can and should be able to do this (?).
This is why I believe I cannot gain speed in swimming and why my breathing is difficult.
Do others have an easy time with this drill? Fooboo, can you do this??
