Oh ya I've heared that to. I'm the only one in may family who eats health, I will assume your the same way?
Have you ever done pilates? My back has been going out for years where I would go to the chiropractor 3-4 times a week, after I started teaching pilates I go maybe 1 time a year if that.
Yes, I am the only vegan in the family. My family thinks they eat healthy. Chicken, low-fat yogurt, diet soda, etc. If they eat fruit, it is usually encased in Jello.
I have done some pilates, but do mostly yoga, Kung Fu, and P90X. The two things that really helped my back was moving my wallet to my front pocket, and getting some tighter abs. I haven't had my back go out on me in about three years. I tweaked it a couple weeks back, but it was just a little sore for a couple days. When it would go out in the past, I could only walk hunched over and looked like a caveman.
