After oxygen, water and food... the next most important ingredient for good health is exercise.
Here's the short-list as to why:
What type of exercise is most beneficial?
For general good health, any exercise that builds endurance, rather than speed or strength, is best. (But a moderate amount of strength training helps prevent bone-mass loss.)
The best, most natural exercise you can do is walking.
A brisk 30-minute walk every day will transform your health. My husband and I either walk or use our mini-trampoline. (The mini-trampolines are GREAT... I walk on mine during every commercial while I'm watching TV. It's keeps me out of the refrigerator!)
Can't find an interrupted 30-minute block?
Studies at Stanford University and the University of Virginia both demonstrated 3 strenuous 10-minute periods are just as beneficial as 1 interrupted 30-minute session.
Sedentary middle-aged individuals participated in a three-week study at the University of Virginia. They did 15 10-minute sessions per week (the equivalent of two and a half hours of exercise per week) of walking, stretching, and light weight lifting.
They were able to improve aerobic fitness by 15-20%, increase strength and muscular endurance by 40-100 %, lower cholesterol levels by 15 points, and lose an average of three pounds.
