Dowagers hump

I’m 31 and recently have started an exercise program consisting mainly of running and yoga, I find they compliment each other nicely. My shoulders and neck naturaly hump forward so I look like I’m slouching and I frequently have pain in my upper back. Could you suggest some asanas or a series of asanas to help corect my posture and back pain. I have heard that slouched shoulders and upper spine cause ineficient breathing. I would love to start looking after this problem now because I’m sure it will only get worse with age. Thank you

I would suggest focusing upon strengthening your lastissimus dorsi and middle trapezius muscles.  Poses that will do that are cat sinking to also emphasize serratus anterior muscle plus bridge, cobra, and camel.  This posture may diminish your capacity for intercostal motions of respiration.  empahsize that also by pressing on lower ribcage as you exhale.  namaste  Mukunda
