Exercise is important for people of all ages, especially seniors, who are more prone to certain health problems. Ailments such as heart disease, osteoporosis, and arthritis can hamper quality of life. Along with proper nutrition, however, exercise can go a long way in ensuring your loved one leads a happy and healthy life. Something as simple as a morning jog can help one stay in shape. For seniors however, outdoor conditions can sometimes prove dangerous, particularly if they have problems with vision or balance. Fortunately, here are exercises that can be done at home with little or no equipment.
