I may struggle to explain this, how I feel in the water, may not be how I look? I've been working hard on my catch and pull. I used to swim with what felt like a slight glide with a low stroke rate. As I fatigued the glide would become exaggerated and I'd slow down even more. Anyway I've been working on my high elbow and now swim with zero glide. I'm definitely catching much more water, much more powerful in the water, but it feels weird and doesn't feel like what I'm doing is what I see top swimmers doing. My arms are almost like windmills as in moving continuously and it feels like I'm making circular movements. As soon as my hand enters the water it starts the catch and pull. Doesn't feel like what I see in Grant Hackett's video, that's for sure! I'm swimming quicker which is good, but just want to make sure I'm on the right track.
