I've been doing them religiously! Something must be working . . . I've been trying to get my back into shape after injuring a few weeks ago, and my wife and I were practicing out on our practice floor, and she said I felt different, as if my lead were coming much more from my center (and all this time I thought I had been doing that). Anyway, she also said I was somewhat harder to follow, but she definitely could tell where I wanted her to go by just my center. She said it was something about my arms, but couldn't pinpoint it! Maybe too much arm? It's probably me being somewhat stiffer due to the injury along with the exercises that I've been doing. I'll try again this weekend, if not during this week! I'll let you know!
