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.
The difference with land based versus water based movements is that when you jump you throw your arms up while your feet are still pressing on the SOLID ground. If you swung your arms up after you feet left the ground the would reduce the height of your jump. Unless you launch your arm by pressing against the water you are essentially doing the recovery in the air and as your muscles throw the arm forward an equal and opposite force is pulling backward on your shoulder and body, so you slow down when you start the recovery and then speed up at the end as the momentum in your arm pulls your shoulder forward.
In any case, the magnitude of the forces involved in your arm momentum are going to be relatively small in relation to the forces in your pull, I would concentrate your efforts there.
I know this is becoming a physics discussion :laugh2:, but here's my rebuttal. I think that the catch, while not pressing against solid ground, is analagous to the solid ground in a jump. Tomorrow I will do an experiment. I'll lay in the water on my side, both hands on my hips. Then I'll swing the top arm forward and see if there's any movement.
