Kicking rhythm?

I am happy to pass on what broke me of the 'core-less' stroke. Harped on a ton, but body position doesn't happen by accident. And as you probably already know everything is tied together so having a properly timed kick is made much easier by having everything working together...IMO. Stand proud, swim proud. Scapulas retracted/shoulders back or simply....don't slouch. Make sure you kick from the core...not snap at the knees. Plantar flex those ankles. The abdominal group you want to feel is the transverse abdominus, NOT the rectus abdominus. Rectus is the 6 pack ab group, transverse is the deep spinal stabilizing group. When you are reaching for something on a shelf that stays just out of reach, stretch stretch strech.....still can't reach it. That is what you want to feel. Don't let that go and keep it there....all the time. It's really easy to release that core tension towards the end of your pull through so be aware of that and keep that good tension there. This isn't 'watch me squat 500 lbs.' tension, just enough to turn the muscles on so they are in the driver's seat. The metabolic cost of doing this is huge early on, but it will pass and then become second nature. 50's were hard for me to keep it together at first. Now I can do 500's....and so will you! Slowly at first and then it will come along fast in adaptation. Good luck and have fun you are on your way to good stuff! Oh, I hear you, but this feeling is so elusive and fleeting for me. If only I could hold on to it. But I get tired or something distracts me (like a flip turn) and in a second it is all gone. I am working on it, though... everyday, or at least every time I have a chance to get into the pool but I am working against 40 years of bad habits and I know it is going to take some time. Any ideas/thoughts on how to hold on to that feeling would be so appreciated.
