Cracking, popping, or adjusting the upper back alleviates tension, knots, and pain. To align and adjust the upper back and part of the neck, the technique is simple. With your right arm, cross it over. Then with your left arm, hook it to the right arm as a guide. Then swing 3 times. On the third swing, pull the left arm towards your left side. You should hear a crack, pop, or some kind of adjustment. If you are lucky, your neck will give in, and you may probably hear a neck pop. Finally do the same on the other side. Please consult your chiropractor, doctor, or physician. Aligning your own body can save your back, but having a professional will give you a better chance.
