A new way

The other day I got a copy of the swim stroke analysis video that they used at the Triathlon Boot Camp to analyze my stroke. Unfortunately, there is no "after" video to show the results of the coaching that they provided - which was excellent.
Back in "the day" we were taught to try and keep our elbows pretty low to the water and to swim with our heads tilted ahead and with the waterline roughly across our foreheads. The new way teaches a stroke that gets the elbows very high for a steeper angle on the reach with the head facing straight down with the waterline roughly perpendicular to the top of the head. This allows a much fuller "roll" from one side to the other. The theory is that the stroke is strengthened by engaging and getting power from the hips and the "core". This seems to work very well. If you check out some Olympic swim video and pay attention to this you will be amazed at how full their body turn is - and how high their elbows get out of the water.
The coaches pointed out that while I have a pretty good reach and glide in my stroke there would be a big benefit to getting my forearm set in a more powerful position (bent at the elbow) earlier in the stroke. That makes sense and I've been working on that - along with the other stuff.
I was pretty critical of the fact that my rear end seems to be "dragging" through the water - but, I guess that is a bit of a reflection of the fact that the "Endless Pool" machine tends to move water at the surface only which makes it harder to keep the legs up.
The "vortex" of bubbles from the stroke look pretty cool.
