I have a workshop I do on mindfulness, which one might say is the yoga variant on wellness. It would be hard to give you those resources out of context, because I find a workshop works best when one adapts it to the needs of the people in the room. In other words, I know what I want to say, I have handouts, I have a structure to how I want to address the topics, but the particular tools I use, and the direction we go is always a little fluid. The more the people who come feel that they are participating, and the more their questions are listened to and answered, the more the group engages with each other as a group, the more they will remember, take away, and be empowered to take into their daily life.
I would like to give you one or two suggestions though.
Take time to have lists of local resources. For example I can tell people about the mechanics, history, and philosophy of meditation, but a list of local groups where they can go to practice is essential.
The same with nutrition. Unless you are a registered dietitian or certified nutritionist it is important to understand and stay within one’s scope of practice… and the more you try to tell them the more they will ask for detailed answers to their own situations, and the more of a false position you can put yourself in if you try to diagnose or treat. If you have a list of local nutritionists, especially if you can personally recommend any that is excellent.
There is a book called ‘The Pen and the Bell’ you might like to look at. It is a series of prompts for writing exercises designed to heighten mindful engagement with the world. What is good with using something like this is that you can use one of these prompts to engage them actively, rather than simply lecturing them.
I know you wanted something more practical, so sorry if this is too general. Good luck with this.
