Stance....hands, legs and feet...carver skateboard

Been working on following the info in these two videos lately....have found them very useful and am seeing positive results from the info used. I have also found muscles in my legs that I'd forgotten about! Been following and drilling the principles in water, but it is on the carver skateboard that I can really put a lot of time in riding (half hour on the skatey equals a half hour riding time....no idea how long that would take in the water....). Kinda squeezing the knees together and the mental image of keeping the hands outside the body line on either side (exaggerating the movement at first) has helped me make inroads.....These are the vids:
