It’s easy to over complicate swimming; once you get the fundamentals right, the small details often naturally fall into place.
I use video analyse in all my sessions which is an invaluable too for helping you understand your stroke. 
Having swum competitively as a junior,  I came back to swimming in my late 30’s and realised that the skills I had developed for sprinting as a junior did not translate well to swimming longer distances.  I embarked on a journey of learning how in order to be efficient moving through the water, a swimmer needs to be balanced and the stroke needs to be connected to body rotation.
