Mike, thanks for your encouragement on my exercise.
I got my exercise done--did find a 10 minute beginner step aerobics demo online and used a shallow step in my sunken living room which worked well, especially considering my basement vision blind spots from glaucoma. I knew where the step was and that it wouldn't move, so I knew I wouldn't fall. But I was only able to complete the first 4 minutes because my hips got tired. Finished up the other 26 minutes with moves I know from my cardio class at the Y and from my aerobic walking DVD, some power walking in place, and some AbSlide reps.
Wishing everyone a great Sunday!
