Is this type of practice also beneficial to a person who still has basic issues? Issues like legs not being straight, streamline, still experiencing drag?
I have tried this on 3 separate occasions and have gotten widely varied results--nothing like what others have been reporting. On the first 2 tries, I was using a very exaggerated 2 beat kick with legs flailing alll over the place. On the last try, I got increased spl but I was less tired and not out of breath so much.
I guess what I am asking is at what stage do you start introducing some of these sets?
