Asking Eric: Show-off at exercise class got worse when I talked to her about it

Dear Eric: I am a recently retired woman who is appreciating my morning routine at the gym. I love the group exercise classes. My issue is with one woman who insists on counting very loudly with the instructor, slipping in loud singing with the music and thinking she is entertaining during class.

She does it during every class twice a week. The first few months of classes I let it slide. I finally, diplomatically, took her aside and told her that her loud counting and singing is very distracting to some of us taking the class.
