Phelx Swim has a good channel. The Race Club is another one that is really good.
... Swimswam has their Practice & Pancakes series that shows some good sets, some might be a bit advanced but some can be scaled.

I track my swims with Phelx.



My main set today...

The first and best resource would be an experienced swim coach and swim daily on a team. Then weekly one on one sessions with coach.

In terms of online resources, it would be:

GoSwim.Tv, The Race Club

ASCA archives
Swimming World archives

Swimming Fastest
Swim Coaching Bible Vol 1 & 2

There are a few others but they are very specific.

Hope this helps,

Tim
