Depending on how old, and how fit you might consider a chair yoga workshop. For a very fit community it is not as important, but all the places I work that offer chair classes are well attended…. for adults of any age with joint issues, or balance issues, or recent knee replacement, or recent surgery of any kind, there are some great techniques for modifying yoga to be done seated, or standing and using the chair to help balance.
I would find it helpful if you could qualify your question because I am confused between your statement of an ‘older community’ and the fact that you have offered an intro to kettlebells and free weights but have upcoming flexibility and balance.
Are you addressing the same people?
How about a workout design workshop? You can discuss how much cardio, strength training, flexibility work to include in a daily/weekly program for the average “older” client. How they can progress their workout, focusing on all body areas.
Or if you have an event in your area coming up, how to train for that event? A 5K walk lets say.
You can also poll your audience to see what they’re interested in learning more about. You may get some better ideas from them that are then geared right toward the audience you’re trying to reach.
thanks for the clarification.
People often enjoy learning about fitness related to a specific sport like running or golf. Alternatively, low back health and what to do and not to do to maintain healthy shoulders may be areas of interest.
