Overhead is a three-part movement
Getting your arms fully overhead needs the shoulder joint to rotate, the shoulder blade to rotate and tilt on the rib cage, and the mid back to extend enough to let both happen.
Yoga asks for that combination constantly: downward dog, upward salute, wheel, forearm balances, most inversions. When one of the three parts is short, the others compensate, and the most common compensation is arching the lower back to fake the last few degrees.
If your teacher keeps cueing your ribs in down dog, that is what they are seeing.
Testing where you are short
Stand with your back against a wall, heels a few inches out, lower back gently flattened. Raise your arms overhead and try to touch the wall with the backs of your hands without letting your ribs lift.
If the hands do not reach, note where the movement stops and what stops it. If you can reach easily once you let the ribs flare, the range is coming from your spine rather than your shoulders.
This is a self-check, not a diagnosis.
The routine
Eight minutes, lightest tension.
Standing rotation, 10 per side. Mid back first. Rotation and extension share the same real estate.
Overhead side bend, 8 per side. Reach long, breathe into the open side.
Scapular set-and-release, 10 reps. Bar at chest height, draw the blades down and back, hold two seconds, release completely.
Reach-and-row, 8 per side. Shoulder blade leads, elbow follows.
Pass-overs, 10 slow reps. Widest comfortable grip.
Overhead hold, 4 rounds of 20 seconds. Ribs stacked. This is the one that transfers most directly.
Tall-kneeling overhead hold, 2 rounds of 20 seconds. Take the legs out and rib position becomes obvious.
Cues that transfer to the mat
Lengthen before you reach. Getting tall creates the room to go overhead into.
Ribs down, always. Applies equally in the routine and in every standing pose.
Shoulder blade leads. In poses and in drills, the blade should travel with the arm rather than catch up afterwards.
Progression
Hold duration first, then grip width on pass-overs, then tall-kneeling, then tension. Weeks, not days.
Limits
Shoulder pain in overhead shapes is common and worth taking seriously rather than stretching through. Pain that is sharp, that wakes you, or that comes with weakness or numbness needs a qualified professional.
Common questions
Why does my lower back arch in overhead poses?
Usually because the shoulders and mid back are not supplying enough range, so the spine borrows the rest. Training all three parts of the overhead pattern tends to reduce it.
Can I use the bar in class?
It is designed for a five-minute block before or outside class rather than during it.
