To maintain a healthy body as we age we must be willing to invest time into exercising. Exercise builds bones, muscles, improves circulation and ensures our body is functioning optimally on all levels. We do not have to become body builders and spend hours each day at the gym in the name of physical fitness. There are many exercises we can do at home in a short amount of time. One such circuit is what we like to call the sexy legs challenge and it takes about 15 minutes. Your body will thank you for this small investment of time and you see noticeable differences in a relatively short time frame. Challenge yourself to do this workout a couple of times a week for the next month. Clear a space in your living room and lets get to it.
