My mom, daughter and I joined Curves together. I was told it would help my health problems, mainly COPD and fibromyalsia. However, the first week I got bronchitis and could not go for awhile. When I went back the instructors would not let me exercise, saying it was too dangerous because of my breathing. They said I did not need to work out while I was having breathing difficulty, I always have breathing difficulty. Since then I have had bronchitis numerous times and therefore have not gone back to Curves.
