Hi, all. I just started Foundation One and I have a question about RC/PE1>iM. The focus points for this exercise say I should sit strongly and feel the lat relax. My question is about how I'm supposed to hold my shoulders? Am I supposed to complete relax the muscles in my shoulder area, or should I maintain muscle tension to stabilize my shoulder girdle while relaxing my lat? I ask this because I feel my left shoulder is less stable than my right, and my ability to sit back and stretch is probably much stronger than the ligaments' ability to hold my shoulder together for a long time. Any input is appreciated. Thanks.
