I am a 45 year old Black woman, and overweight. I have been on asthma meds for 7 years. In the course of this time, I have developed muscle weakness from the albuterol, Advair, etc. I have tried working with various exercises to strengthen my muscles, but my knees hurt. My knees have been weakened as a result of the medicines too. I have had more falls and injuries because my knees give out completely. Therefore walking or leg exercises is a chore. I take a muscle builder "glutamine", but it's not effective if I don't work out.
Is there any thing that can counteract this weakness (i.e. supplements, herbs, etc.)or an exercise that would be effective, but not hard on my knees?
At this point, I am trying to lose the weight, to keep from having a knee operation, but it is getting hard to resist, plus the doctor wants me to lose the weight. Any suggestions would be appreciated.
