The first five minutes of this class are a tutorial about safe movement for clients with bone density issues. That being said, I think this class is absolutely appropriate for any client. Props used include a small towel, a light resistance band, a tennis ball, a Pilates ball and a Carex roll. (https://www.amazon.com/Carex-Lumbar-Lower-Support-Pillow/). You can easily do the class with just the Pilates ball, the other props are optional.
