Winter increases a senior’s fall risk because of snow and ice, so indoor activities are usually safer during these cold months. To stay active, seniors can join a gym and take fitness classes or work out in the gym’s indoor pool. They can also make use of YouTube exercise videos, stream exercise shows, or purchase workout DVDs to stay fit at home. For outside activities, such as walking or jogging, be sure to layer clothing, know the signs of hypothermia, and check weather conditions before heading out.
