Fitness nursing

[Anhodgetts7]

Hello! I've been an RN for 5 years now - working with the geriatric population and most recently hospice. I'm a 10 time marathon runner and into healthy living and a healthy lifestyle. I am very interested in shifting my career and would love to work with people from a fitness/nursing level. I have yet to decide on the targeted population but I'd like to be able to work on diet plans for disease processes, workout plans to meet the patients needs, disease prevention and disease education. I have NO idea where to even start with this. Has anyone pursued anything like this? If so, how did you start? Have you been successful? What would you recommend? Thank you!
