Advanced Muscle Control – Strength Magazine – April, 1929

Last month we left off with the exercise for stretching and strengthening the abdominal muscles in preparation for performing the feat known as the “Rope,” or vertical isolation of the rectus abdominus muscles, shown in Figures 1 to 4, Figure 1 being the most desirable effect toward which to strive. This feat is one of the most difficult of all, and is one which requires some time and patience, plus concentration, if one is to learn it.
