Progressive Angular Twist
Grab both ends of the towel about shoulder-width apart. Relax the shoulders down and back and extend arms forward at shoulder height, keeping a slight bend in the elbow. Twist towel to the left, raising right hand slightly and lowering left hand, then switch, twisting in the other direction.
Start small, twisting about 10 to 20 degrees in each direction. After one eight count, progress into a medium-size twist, and for the third eight count, twist a full 180 degrees so the towel is vertical and one hand is directly over the other. Progress back to medium twists and then small twists for one eight count each for five eight counts total.
