Still waiting to see some one talk about getting under the backwash (all the water you drag into the wall with you), which is physics.. How deep, how far do you have to go to get out from it. Phelps is a master of this. Also, Both butterfly kick and flutter kick are 'crack the whip' actions. The fly is a total body wave type crack the whip, from arms, head, and shoulders to to the tips of your toes. The flutter kick is still crack the whip, but the energy transfer from shoulders to toes is a spiral/torque motion similar to throwing or kicking, but they are more of a push, and swimming is a pull. The kick that syncs with the shoulder pull/rotation is the stronger one...
A few of the terms thrown around are sloppy physics. I do have an undergrad in Physics so I get particular about it. Momentum is not force. The term "torque" herein used seems meant as a way to initiate propulsion. Maybe yes, maybe no - or, put a different way, not exactly. The video correctly point out that torque will tend to drop the feet as the body rotates around the center of mass during the stroke. One thing that would have been interesting is to use instrumentation to measure drag when towing swimmers of different shapes, using different swimwear, caps, no caps, etc.. Body type goes a long way toward making a low-drag swimmer. I am a former runner just three years into learning to swim and I find I am still very, very slow in the pool despite having had decent speed running and cycling.
Great information. Background music is too loud and totally unnecessary.
Great video. I learned a little, but mostly just enjoyed seeing all the concepts presented so well.
really great video, but the music is distracting.
Great video. Lots of information to digest. Thanks.
ah i love this. used it for a school assignment and gave you HUGE credits. thanks for that(:
is it possible to get this video without the music bed?
Excellent video! I learnt a lot.
Very good presentation. Keep up the good work.
Great video, thank you
the background music is too damn loud !!!!
Ashley, don't listen to the critics (except for the music part...). Make more videos about swimming.
Great video!!!!!!

Great!!!
The music is waaaay to loud. Can't hear the narrator. Can't really watch the video.
loveeed it
Good vid

Is this a rock concert ??
Volume is too high. I couldn't make it to the end. 😞
