What I think I need to improve is the following:
-more relaxed and smaller arm movements. This is hard because I was taught to use my hands vigorously while swimming before and this is counter intuitive for my brain
-flipping my body on the side when I breathe. I think I rotate my body too much, but because of all the skating drills where you get to breathe pretty much on your back, it's not easy to find the sweet spot.
-continue working on the bilateral breathing
-more relaxed head position in the water. I know that I still lift my head up to breathe sometimes, so I need to become less stressed about not breathing long enough, efficient enough or swallowing water.
That's about it for today. I hope to be able to go and work all this in a "real" pool next time. At least 25m wouldn't be too much to ask, right? If only time permits, because the 25m pool only has the 9-10pm window open for adult swim. Quite a shame, we need more pools!
