Why it's first
The floor does two things for you. It holds your rib cage still, so the anchor can't wander. And it gives the shoulder blade a surface to press into, so you get feedback about where the blade is. Standing up, you have no way of sensing that. Most people feel the serratus for the first time here.
It is also the only exercise on this page that picks a side. You reach with the arm on the side that wings, because that is the blade nothing is holding down. Doing it with both arms at once lets the good side carry the movement, which is exactly what you are trying to stop.
How to do it
- Lie on your back, knees bent, feet flat on the floor.
- Raise the arm on your winging side straight up toward the ceiling, wrist stacked over that shoulder, palm facing in. Left blade winging, left arm. Right blade winging, right arm. Your other arm rests on the floor at your side, palm up.
- Exhale slowly through pursed lips for five seconds and keep going past where you'd normally stop. Let your ribs settle toward the floor. Your low back should get closer to the floor, not further from it.
- At the bottom of that exhale, reach that hand straight up toward the ceiling. Straight up, not forward over your face. Let that shoulder blade come an inch off the floor and slide wide around your rib cage.
- Hold the reach for three seconds with the air still out. That hold is the exercise. Everything before it is setup.
- Lower the blade back to the floor over three seconds. Inhale quietly through your nose without letting your ribs pop up or your back arch. Then go again.
Both sides winging, or you can't tell from your Day 1 clips? Run the full set on one side, rest, then run it on the other. Never both arms at once. One blade at a time is the whole point.
You've got it when
A warm, working feeling along the side of your ribs under that armpit, and spread across the back of that shoulder. Low back stays down the whole time. The other shoulder stays heavy on the floor. Neck and jaw completely quiet.
You've lost it when
Your ribs lift and your back arches off the floor as you reach. Your head comes up. Your whole body rolls toward the reaching arm instead of the blade moving on its own. Your shoulder travels toward your ear instead of your hand travelling to the ceiling. Or you feel it in the front of the shoulder. Reset, take less range.
