I was a competitive scull. Perve on the women was the most I remember as advice from my coach. Woman weren't pulling the skin off due to their less might filled muscle, they were talented with balance, smooth transactions and really nice scull racks.
As purr basics, ,, legs, torso, arms in that order. Reverse and slow to recock catch.
A wrong example. If I was to catch (water grab with blades) and then straighten my back before I pushed my legs, my back would be bowing due to excess force and my legs would be reduced from 60%(overall stroke input) to 30% plus slight bit of nothing.
ALWAYS push with legs then straighten back then finish with arms.
Push away with arms then lean forward then bend your knees, while maintaining glide.
AND PERVE ON THE WOMAN. They have best techniques. Ma star luv pasta.
