freestyle changelog

1. over-kicking issue that consumed all the energy fixed. two kicks per handstroke now.


2. arms need to "cut" through the water. this fix gave the correct body roll.


3. leg kicking motion changed. instead of kicking with lower part of legs or keeping knees locked and kicking with full legs, legs assume a curve to kick in the water like ribbons moving in the wind.


4. breathing changed. instead of taking long deep breaths, big mouthfuls of air are simply gulped in and breathed out.


5. body axis maintained by stomach muscles for smoother breathing.
