I've just watched the video by Swim Smooth on instagram:

The description mentions;
Now take a closer look at the amount of kick required to sustain such a long, gliding stroke in the first clip - it’s huge! I can barely hold this pace for more than the 70m of this clip! I’m totally exhausted and starting to drop off @karyn_aus and @rrobbo83 pace.
But my question is: How the heck is he possible to sustain 74 spm for 3 km? Won't such a high stroke rate tire the arms and the whole upper body a lot?! And for the 46 spm swim, why he is kicking so frequently? If he can do 46 spm with 2-beat kick it would be PERFECT for extra-long distance swim, which I am aiming for.
