While visiting Palo Alto Swim Association, Coach Tisha showed us many cool techniques in her teaching. Here's a very simple one.
Why do it:
When working with developing swimmers, sometimes you need to get the point across of WHAT NOT TO DO. When teaching streamline, if the swimmers aren't getting it, show them the opposite of what you want.
How to do it (these are pretty self-explanatory... Create resistance):
1 - Push off in the "Y"
2 - Push off in the "T"
3 - Push off in the "A"
4 - Push off in the "X"
5 - Get back to the "I"
How to do it really well (the fine points):
This is the standard OVERTEACHING used very often by teachers. Show them the extremes of the little mistakes they're making, like hands apart, or feet apart during the streamline.
Have them check how far they go each time to further make the point of the proper streamline being THE WAY to leave the wall.
