Dariusz,
At 02:120 in the video I posted yesterday, you will notice that my right heel loses contact and slides left when my left arm is parallel to the ground. This proves that the force in my feet is in accordance with your end of backswing arrows in "Top" Step 3, but it doesn't transition to rolling to the inside of my right foot like you show in the "Mid Downswing" Step 4. I can tell you that my DryJoys will not allow me to roll my right foot like I see with Lee, Hogan, and Fred Couples for example. I have tied my shoes as tight as possible and it will not roll. I have kept my right foot arched so my ankle is stiff and it will not roll. How to you get the forces as you show in 4. Apparently, I am doing something wrong there and I think it must have something to do with the movement of my hips, upper body, or hands or is it the shoes...I am not sure how to fix this after 12 weeks of dedicated effort. The only way it can keep the right foot down is to pressurize to the outside of my foot, but then they are flat but not rolling so this is incorrect.
Thanks,
Rock
Rock,
First, why would you like to keep the rear heel down at impact ? E.g. Hogan did not do it. IMO, there is time the rear heel stays on the ground and there is time it loses contact with the ground unless there is a conscious pushing down via the rear side. The best would be if Elk could chime in and just describe his feels about it. What I can see in his swing is that his rear knee sort of collapses down (as he wanted to add more power) and the result is rolling the entire foot down without losing contact with the ground.
Now, if you're unable to roll the foot inwards (which is independent issue of keeping the heel on the ground) IMO either your rear hip joint motion is incorrect (usually because footwork is incorrect, bad positioning of feet, no presets, too late pelvic CoG shift, etc.) or your rotational RoM in both knee and especially ankle joints is limited and below average (pay attention to Park's post).
Cheers
Dariusz, could you describe correct rear hip action that would result in not losing the "tush line". Thanks! Rock, you have evolved to the million dollar question.
