Feeling Achy? The Body Part You Don't Know You Have

You have six times as many sensory neurons loaded in your fasciae as in any other tissue of your body except for your skin, explains Jill Miller, a fitness expert and longtime fascia evangelist (she's an experienced registered yoga teacher, has presented case studies at fascia research conferences and developed the Roll Model fascia therapy program). This internal webbing helps different muscle systems communicate with one another—they're what make you want to get out of your office chair and stretch or roll your neck around. Ideally, your fascias should be supple enough to slide, glide, twist and bind like long, thin sheets of rubber. When they're not functioning properly, signals from the nerve endings are muffled or muted (so you don't feel comfortable in your own body) or they're interpreted by your brain as pain and discomfort.
