Once we turn 50, we lose about 1-2% of muscle mass each and every year! As of the age of 60, muscle strength diminishes by some 3% yearly. This loss of muscle strength, mass, function and volume is defined by the medical term "sarcopenia". Adults who have been active throughout their lives are less prone to experiencing this debilitating loss. In fact, so to speak, we can stop the clock, or at least slow it down, and maintain as much of healthy, strong muscle mass by exercising daily and eating healthy. To do this, we need to incorporate in our program some safe weight training, as well as increase the amount or proteins consumed. Both of these factors will have the most impact on building the healthy muscle mass at any age! The 2008 Physical Activity Guidelines for Adults and Older Adults recommended to weight train at least twice a week, on top of all the cardio training time. Make sure to create some time and space to accommodate this component, so important to your general health and well-being. Let me know if you have any questions regarding designing a program which would be right just for you and starting you on the path to health! It is never too late!
