thank you for the explanation. It sounds like a blog in a way. I am trying to keep up with sparkpeople, but recently i have just been keeping up with the mail and maybe the sparkpoints. I have not been motivated very much.i definitely need to get since i am over 50 but my biggest problem is being addicted to sugar. my weight is 170 pounds right now and i want to go down to 125 before the end of the year.what i am basically looking for are easy exercises that won't strain my back since it tends to hurt after a short time of exercise.years ago i use to do repetitive movement for 8 hours a day where twisting my body was involved the whole time. my doctor at that time i was suppose to use my back brace most of the time, but i stopped after awhile. I have a back brace now, but i do not use it. I just do not know what to do. I was hoping you could help tell me the best thing to do.
