9If you think aging is a passive endeavor, you are wrong. We don't stop using our bodies to propel us through our daily lives because we've reached a certain age. We become sedentary at our own peril. Instead of becoming weak, learn how to stay strong. Instead of risking a fall, learn how to be stable. It only takes three hours per week to build muscle, improve balance and stability, and slow bone loss. And resistance training offers even more benefits, such as a lowered risk of a heart attack or stroke. Train to Age is about more than cardio and resistance training. It's about all the things you want to do with the last third of your life. You can passively walk through the process of aging, allowing its degradations to take away your strength and eventually your independence-or you can Train to Age and live your best life well into your eighties!
