Well, my story is not as impressive as Rozy's (wonderful job!!!), but I am nearly finished with my personal metamorphosis.
I am 46 and have always been overweight and sedentary. Two years ago, right after New Year's, something snapped, and I knew that this time would be the time I changed my body and habits for good. I started out doing only Ravi and Ana dvds because they were easy enough, moved slowly, and I could workout with my eyes closed and rest between poses. I ended up making exercise a 6-day-a-week habit and cleaned up my diet.
I have lost, so far, 43 pounds out of my goal of 47. I love to workout now and do so 6-7 days a week. The food in our household has totally changed, so I don't consider this a diet at all but a lifestyle change.
So, that's my little story.
