i am not sure if this is true, but i think when people say the shoulders move the arms to the top, i think they are meaning your arms should not be moving up once the shoulders stop. so as long as your shoulders are moving then it is okay to move your arms up... just a guess though.

i always think of the motions being 2 seperat things when i swing back.

here is a good link of tigers swing in slow mo http://www.youtube.com/w/Swing-Visio...page=1&t=t&f=b

maybe this will help
