Older adults are my favorite group to work with. I always start out with a balance assessment just so that I know what they are capable of. It also helps build their confidence a little bit because I find that a lot of them can do more than they think, they just lack the confidence.
From there, I do many of the things that other people have mentioned, but I always make sure I have a variety prepared. Some people absolutely won’t try walking without a walker, but they can stand on one foot with their eyes closed without holding on to anything. I try to stay just within their comfort zone, but still make it challenging. Anything that I can turn into a competition also seems to work well. We do obstacle courses, workouts tossing balls around, and walking interval workouts and most older adults generally enjoy all of those. You may look at the ICAA website for more ideas (www.icaa.cc).
