This has been a constant battle for me to get my DD to stay open more. What are some good drills I can use to work this out? I've been trying to make some changes to her motion. She was using the big bent waist backswing like Abbott. I'm trying to convert her to more of an upright motion. Since I've started changing her motion she closes to early causing her left foot to step to the left of the powerline. I had her do some K's with her back against a fence today so she can't crank her shoulder sideways. It seemed to help.
