Excellent, thanks for the reply. If the rear hip is the power source, what should the feel be? Is it a glute/hammy extension? Aimed at the target? I only recently started to try and feel this extension after @Bonesaw had talked about it. I know that i have focused more on torso upper body power. So would be nice to give her another cue.
I think a distinction should be made between pelvic tilt and flexion/extension.
If you say anterior pelvic tilt I think this
If you say hip flexion I think this
Big difference.
