Hello Cynthia Polk-Allen,
Yes, you should be covered for all health and fitness training with one insurance policy. I signed up with the company that you can find through ACE and IDEA and told them what I do which can and should be updated when you go elsewhere and change your services.
Natalie aka NAPS 2 B Fit.
Professional liability insurance will cover you for group fitness & yoga. Make the insurance company aware that you want coverage for group fitness & yoga, etc.
The professional liability coverage I have covers me for personal training, group personal training, group fitness, & any other classes that are fitness related.
Professional liability insurance is relatively inexpensive. Check with your group fitness certification organization, they often offer liability insurance with a discounted rate.
