Keep hands from sitting low; align shaft to forearms
The instructor calls it a key fundamental in good putters to have the putter shaft in line with the forearms and the hands not too low. Hands that sit too low let the putter's toe come up and cause a loss of control over the face angle. They reference a Steve Stricker or Aaron Baddeley setup as the position they say not enough golfers get into.
