I am 19 years old. Not too noticeably fat but VERY out of shape. Is it normal to hear my bones snap and pop when I stretch or rotate my shoulder blades? It doesn't hurt, just makes alot of noise? If it's not normal, can anyone tell me why this happens to me and not other people?

Actually, this happens to me, too. I'm thinking it's just cause it's weak.

synovial fluid has bubbles in it. when the bubbles pop, it makes a snapping noise. That's what the noise is when you crack your knuckles. Does it sound like when you crack your knuckles?
