NY DAD...Do you see your sons hands being pulled by the rear leg drive inward?
Do you see rear leg drive inward in your son?
Do you see rear hip coil in your son like the rear hip coil you see in Edmonds above?
Do you see the rear leg pulling the rear hip forward into rotation on Edmonds?
What about your son?
My answers below to the questions.....
1. No, Because his hips are causing the hips to rotate. Hip rotation should be caused by the leg drive and not the hips....which is "why" you see his lead leg do what it does.
2.No, your son never coils around the rear leg he sway back onto the leg. That is not coiling.
3. Yes, Edmonds rear leg is pulling everything above it sequencially up the chain.
4.No, your sons rear leg is being pulled inward by the hip rotation. Opposite of what Edmonds is doing.
Here is a 15 year old from this site for comparrisons to help.
