I have recently been told by my rheumy that I should do at least 20 minutes of aerobic exercise 3 times a week. She suggested walking. My heart rate is unusually high. I am a housekeeping business owner, so I work very hard and am usually in almost intolerable pain all the time. I am willing to do the walking, but am wondering about doing some strength training. I get advice to do it and advice against doing it as I am told it could really flare the CFIDS. I have lost about 25 pounds in the last few months and am now doing a high carb, high calorie program to gain back some of the weight. Doctors have been absolutely no help to me...as most of us know, I think. So, as I try to gain the weight I would also like to tone back up, because I have lost so much muscle mass. Any advice would be greatly appreciated. Thank you and blessings to all of my fellow sufferers.
