Dear HB,

Lifting the Left Shoulder is a common posture problem with a common cause and a simple solution. More on that later.

Hogans procedure is typical 10-7-C "Double Shift" and the Double Shift is a common TGM Variation. I'm trying to figure out how you use it to prevent your problem with lifting your left shoulder.

What is it about the Double Shift that allows you to make a correct Backstroke shoulder turn while using a Zero or Single Shift you don't?

Signed,

Curious
