Swim Critique (Video)

I grew up competative swimming since I was 5 through high school, then started Tri's in college.  Did coach a few local teams for a couple years.  Overall stroke looks pretty good.  Your hips and kick looks a little off.  Looks like your hips are a little low and looks like they move a little side to side as opposed to just rotating your body.  Rhythm of your arms is nice but seems a bit choppy try to smooth it out with a few drills like the armpit drill.  Pull your thumb all the way up your side into your armpit but do it very slow and methodical.  Try to get a little more glide out of each pull, drill could be the catch-up.  Work on keeping your legs closer together, pull bouys can help.  Your legs look like they are seperating sideways when you kick instead of seperating stright up and down.  This could also be due to the excessive hip rotation and movement.

Your overall progress and stroke is great though!!!

You and I have very similar builds, stroke rates, and times, so I'll pipe in with a couple things I'm working on, hoping that it helps you as well.

I see in your stroke the same thing that's in mine which is that you rotate a slight bit more on your right side than your left while breathing. It doesn't create a huge imbalance, but it does require a slightly different distribution of strength from side to side, and I find that my right delts are more fatigued over the course of a long swim than my left, which over time deteriorates the stroke quality as I compensate. You might not experience this, but I do, and if I focus on it I balance a little better, which brings me a bit higher in the water/makes me faster.

I'm also working on entering the water more efficiently with my hand and quickly getting extended, which means spearing more at a down angle than straight out in front. Poor description maybe, but I see you do this well with your right arm, but your left arm is flatter in the water on entry, so there's some extra resistance there. Can't see your catch and pull but we can all increase our strength and make that less prone to breaking down over the course of a long swim. Your efficiency is decreasing with each length - you start with 18 strokes, then 19, then 19 again, then 20. I'd guess that after 500 yards or so you're probably closer to 21 strokes per length. I have the same thing going on, which I attribute to strength. 

Out of the pool, I'm always stretching my streamline form as much as I can, until I can wrap my shoulders around my head. Can't be flexible enough.

Also been experimenting with the fact that I occasionally lock up a calf or foot arch after longer sessions. The people I've spoken to suggest it might be low potassium levels, so I'm banana loading before my session tonight to test it out. Any ideas for me? (not to hijack, sorry).

What do YOU see in your stroke you want to work on?
