Before I was harmonized I could only do a mile tops on the elliptical, but after I was harmonized, within one week I went from one mile on the elliptical up to four to five miles without stopping. I used to have back problems when I was younger and still now, as well as stiffness, but it has changed since I was harmonized. Robert even said that I had the worst back alignment he has seen recently and nerve damage, but that changed now. Also, I was introduced to a hidden food allergy to wheat, so I also used a herbal cleansing system to help clear my digestive system and increase my metabolism. My performance is great now, but like they say things will get worse before they get better.
