So I finally got some video of myself and my son up. This is the first time I'm seeing myself swim, and I'm horrified, lol.
My self-critique: Elbows not high enough, not extending arms very well, arms crossing midline a little on extension, and extending hand almost pushing water a little. Please feel free to add anything, and I'd appreciate advice on drills to address my specific weaknesses (and my son's).

My son's critique: Elbows drop some, he tends to pull a little too much to the outside rather than down the middle, and his left arm tends to go left on extension. Believe it or not he's much faster than the last time I posted video, he's gotten his 25m time down to 26 sec from 45 when the season started. Please add anything.

Thanks guys.

in talking to eamon sullivan's biomechanist, he seemed to agree that the sidearm recovery took longer than the traditional bent-arm recovery, but: a) he didn't think it would affect the pull rate of eamon, and b) he didn't explain to me why he felt that such a recovery would take longer. My guess is that your upper arm may follow the same path in both, and your lower arm may be along for the ride, but the catch starts at the fingertips, and it takes longer for those finger tips to get into position if they are following a more curvilinear path. In bent-arm recovery, the fingertips follow tangentially to the smaller semicircular path created by following the movement of the elbow. in sidearm, the fingertips follow parallel to the elbow's path in a larger semicircle. Essentially, where sidearm follows the perimeter of that larger semicircle, bent-arm streaks down the diameter.

to my knowledge, the rotation of the body does a few things. first, it reduces your drag by narrowing the amount of surface area splitting the water. second, it allows your reaching hand to reach that little bit farther that you could only reach by dropping that shoulder. third, it helps convert the pulling hand's final push to the outside to a push behind by changing the positioning of the body and therefore the effect of the push. it's really quite useful.
