This is great information from one of the best ever. I think there’s a rotational aspect of the kick, and to some degree the pull, that I’ve never heard anyone talk about. The feet don’t just move straight back: they rotate 90 degrees during the power phase as the lower legs sweep back together in an arc. This circular or torsion motion of the feet generates power like a propeller, not a paddle. In swimming, sculling is a term typically focused on the hands, but in breaststroke, the feet are sculling in a arc. There is a similar rotational propulsive aspect to the in-sweep of the hands during the recovery phase. It helps to visualize the feet as opposing propeller blades.
If a swimmer is tucking their knees in towards their chest to initiate the kick, they can: kick on their back (hands at side) and think about pulling the heels towards the butt, or, kick with their body against the wall. In both cases their knees are prevented from coming towards their chest, because they would sink if they are on their back, or hit the wall if they are against a wall.
4:42. "generate forward momentum from the head driving forward" Nope, relative to the water you actually pushing yourself backwards! Simple physics. The real benefit is you try to get into the streamline position fast , prior to the propulsion from the kick (kick backwards will result in FORWARDS MOMENTUM.) Good video, just a few misconception in the semantics and perhaps some mistakes in the perceived physics. Thanks (from a physicist)
Nah, Prenot majored in Physics, and he’s correct. When you shoot your hands into the streamline glide, driving your head forward and down to be in the same plane as your body will get the hips up, which is hydrodynamically favorable.

Very useful for my visualisation the different parts of the breast stroke
Breaststroke is becoming my favourite alongside freestyle

such a talent swimmer

No net energy created with the recovery, just transfer of it., and using it for motion no net gain. (From a physicist)
