This is a closed LinkedIn group set up some 8 or 9 years ago that has over 1,400 members. Moribund of late, it lacks the close mentoring and moderating that keeps a small number of people offering open questions for discussion, rather than the current links away to a person’s book or blog.
This could be a great place to discuss the best ways to fix breastroke kick in teaching, or to introduce and teach butterfly at all, let alone the most current thinking on bio-mechanics and fluid dynamics in relation to stroke technique.
Join the group. Start a discussion and build it from there.
