Exercise is a critical component of good health, especially as you age. Exercise will help you:
* Sleep better
* Improve your resistance to fight infections
* Lower your risk of cancer, heart disease and diabetes
* Help your brain work better, making you smarter.
* Delay or prevent Alzheimer's disease
* Lose weight because stronger, better developed muscles burn more calories while at rest, and this can really help with weight loss. So when you exercise try to do a mixture of cardio (walking, swimming, cycling, running, step) and weight bearing exercises (squats, push ups, arm curls, sit ups).
The key to obtaining the benefits of exercise is to find a program and stick to it. Of course, it is useful to have a guide and you will find some under references.
