Tom, I wish this early rearward bat movement stuff had clicked with me two years ago. When I look at clips of hitters like Bonds, Pujols, and Williams now, I just shake my head. I can't believe I missed it. When it finally clicked with me, I worked it into my swing, at which point I had one of those "ah ha" moments. Once you do it, the benefits become crystal clear. I tried it against live pitching and it felt really good.
I was surprised and skeptical at first by Mankin's belief that the early rearward bat movement fixed other common issues such as bat drag, poor connection and lack of separation. After working with my daughter I'm now a believer. I was able to get her to duplicate the movement off of a tee within minutes. What amazed me was how consistent the position of the back forearm was as it turned the corner. You always get that good "V" in the back arm or as some would say "bicep to forearm pinch".
Wellphyt:
My skepticism continues, and was honed by over a year of using Mankin's material with a large number of students. Obviously, that limitation could have been mine, and not the fault of the materials. But my experience was seriously profoundly different than yours. Especially when it came to the swings the girls brought into games / live hitting.
Consequently, clips of you or your daughter demonstrating this success would be valuable to see. Before and after would be great. If you have achieved an improved frame count or demonstrably more bat speed, that would be persuasive to others (beyond just me), I would think.
The experience you are having with your daughter is great. Treasure it, because it seems to end very quickly.
Do you have opportunity to work with hitters beyond your daughter? Would love to hear about the results, how they are performing in age group or college play, etc. Not trying to put you on the spot. Well maybe I am, a little, because as I said, I have had a different experience with your materials than have you. But I think it helps everone to evaluate the efficacy of the information by seeing that it is working.
If you have provided this information previously, I apologize for having missed it. Please don't recreate it, just point me to it.
Thanks,
Scott
