Head-up dolphin kick drill

Have you tried it? If so what was your experience of it? Did it feel useful or helpful in any way? Or did it just feel difficult to do? Does it resemble in any way whole-stroke swimming as you'd like to do it? With any drill or other activity that you don't understand well, these are the questions you ought to pose. I have an opinion on this drill, but first I'd like to know what impressions you've formed. Hi Coach, Thank you for offering your comments. I didn't try it yet, but I assume that I can do it using Zoomers. Probably by reps of 25m. The version I am used to is head lead undulation and hands lead undulation, neutral head position with streamlined body. With and without blue Zoomers. I like this better because it is closer to swim position and it also works my legs and abs. And to tell you the complete truth, I first read these drills from your "Swimming Made Easy" book. Intuitively, I am not attracted by the head up undulation. Because I don't swim with the head up. I guess that this could be a drill to isolate legs work. If I want to work my legs, I would prefer dryland or running. But this is just a personal choice. However, as the head up undulation I saw was practiced by a the Age Group where my daughter swims (they used regular fins for that drill, I forgot to mention). There should be a purpose, and I would like to know more. I could have asked the coach, but I don't want him to mis-interpret, thinking that I could interfer with his business.
