I've been working on opening the hips more to take some pressure off my lumbar spine and try to gain some distance in the process. One thing I have noticed is it's somewhat difficult for me because I preset the hip bump, so I've abandoned the preset hip bump for now...
So far, the feeling I have (which may be completely wrong) is I need to squat early in the downswing and then spring off the front leg to clear the left side and return to proper level with my hips. This is because the hip turn literally elevates the hips. Curious if anyone has a good feel for this movement? Should I not be "squatting"? I'm struggling with a tight lower back right now as well, so that is probably not helping.
Tom's swing makes this movement seem very fluid. The squat is not very noticeable.
