StrongWomen is a nationally recognized nutrition and moderate intensive physical activity program developed and tested by scientists and exercise physiologists at Tufts University. Staying physically active and being properly nourished is one of the most important things you can do to stay healthy for life. Scientific research has demonstrated that exercise with weights (strength training) will increase strength, muscle mass and bone density in middle-aged and older women. Strengthening exercises also reduce the risk of numerous chronic diseases such as diabetes, heart disease, osteoporosis and arthritis. Strength training has been shown to reduce depression and improve sleep, and it contributes to a sense of well-being among older individuals.
