I sent the link to my SWIM VIDEO to coach John (tri coach) and coach Rich (masters swim coach) and got similar advice from both.
1. Press the chest/swim down hill
2. Head neutral / make small movement to take a breath
3. Catch: square the elbows (do finger tip / high elbow drill and catch up drill)
4. Drive from the hips
5. Kick in the bucket
I wrote the 5 things above on a note card I can put in a baggie and take to the pull with me to remind myself of the things I need to work on.
Here is a video I found helpful... how it should be done! The catch.
