Edmonston slides: rotation to gain inches

Not sure where to post this, thought this thread was best since it was sprint based

Charlie and others,

Would you be willing to explain in more detail the rotation to gain inches on each stride from the Edmonton slide? I see how it can work, but for some reason it doesn’t make sense to want to create extra rotation on each stride. AM I missing something?

When your shoulders are down and relaxed and your arms swing normally, they move towards te centerline, causing the shoulders to rotate slightly and the hips to counter-rotate. This causes a net gain of about 1 1/2 inches per stride. Take another look at the graph.

Nothing fancy, just do things right! =) thanks
