improve back posture while sleeping?
sleep without a pillow will help me improve my posture? My neck is coming out my back. (Sway posture)
If you mean by sleeping on your back, no, I do not think so. If you look at someone lying on his back on a bed, without a pillow, you will see that their heads are actually too far back. You really need something under your head to put it upright. If want to have better posture the best thing you can do is lift weights for the back, chest and shoulders. Doing that for a few months while trying to stand during the day do a great job ... Try it and see. Good weight exercises would press for chest, pullup and rowing movements for back, and military presses and flys Rear Delt shoulders. And also some cracks in your abdominals and lower back for laying back.
