FITNESS & YOUR HORMONES
Physical fitness plays an important role in improving the quality of life and increasing a personal sense of health and wellbeing.
Different types of exercise have different benefits:
Resistance training in women can improve both muscle mass and lean soft tissue and may help maintain testosterone and IGF-1 levels. 
A recent study demonstrates that high-intensity interval training (HIIT) reduced cortisol and increased total-testosterone/cortisol-ratio levels significantly in physically inactive adults. 
High intensity interval training and continuous endurance training both improve insulin function. 
However, the combination of aerobic training (AT) and resistance training (RT) resulted in greater improvements in insulin sensitivity, β-cell function, and glucose effectiveness than either aerobic training (AT) or resistance training (RT) alone. 
A conscious effort must be made to achieve and maintain a level of physical fitness to allow your hormones to work properly.
The National Institute on Aging at NIH suggests that an exercise and physical activity program that includes endurance, strength, balance and Flexibility.
