The bat on the shoulder is one way to learn how to use the hands during the swing - it encourages the hands to turn the barrel rather than having the barrel affected by what the arms are doing.
Notice bat on the shoulder. A good model to use:
An important thing to pay attention to in this clip is how she uses the muscles in her back.
Set up a couple of lessons with coach, and she has her keep bat on her shoulder, trying to get force her to load up more for more power, but seems to me swing is slower, and less contact overall now, and confidence at plate is dropping (leading to a couple of Ks looking this past weekend, coach hates this).
Hit with/use your back not your chest.
Further explanation would be appreciated.
I know its off the tee, but I like her HS swing better
Pulling??? I hope I am right! Direction? Around her spine towards CF??
Is she at Purdue or Iowa?
