I use this video with a small group of young adults with developmental disabilities. We love that it is easy to follow, requires no skill or ability to execute fancy moves, and doesn't take much room or any special equipment beyond and light set of handweights. The exercise is basically walking in place with a few simple added movements to break up the time. It includes some mild toning movements built right into the walking and ends with some gentle stretching. All exercises are done standing, so we don't even need exercise mats! I am moderately in shape, and I even get a slight sweat going during the middle of the tape. I think that in addition to seniors, this is also excellent for folks with disabilities or those who have not exercised in a very long time and need something to get them started.
