Today’s lifestyles are sedentary compared to those of our ancestors who were busy hunting and gathering. We spend time sitting in front of computers, driving in cars, and watching our televisions, so many of us need to plan our daily physical exercise. By sticking with those fitness plans, we can increase the number of years we can expect to live. And, regular exercise adds quality to those extra years because it makes us feel better – physically and emotionally.

On average, regular exercise can add two or three years to our life expectancy, according to a study of over 16,000 Harvard alumni, aged 35 to 74. The scientists found that men who played tennis, swam, jogged, or took brisk walks had up to 33 percent lower death rates and a 41 percent lower risk of heart disease when compared to their more sedentary colleagues. Championship skiers and college athletes also have greater life expectancy of four or more years compared with the general population.

Even a modest exercise regimen improves health. Walking 10 to 15 minutes a day, or what adds up to approximately 90 minutes each week, significantly reduces the risk for developing Alzheimer’s disease. Physically active people have lower rates of heart attacks, colon and breast cancer, diabetes, and depression, and these benefits accrue at almost any age. One recent study found that men taking up exercise, even after age 60, can increase their life expectancy.

Routine physical activity may even boost your sex life. A study of approximately 500 middle-aged men found that those who exercised regularly reported more frequent and satisfying sexual encounters compared with their less active counterparts. Another investigation found that the level of sexual activity of middle-aged expert swimmers was comparable to that of the average adult 20 years younger.

By working out on a regular basis, we fortify our muscles, tendons, and cartilage, and increase bone density – all important for keeping our bodies fit and young. The improved strength and balance we gain reduces the risk of falling and injury. Regular exercise also gives us a sense of euphoria by stimulating endorphins – which cause a euphoria sometimes referred to as a "runner’s high." Exercise boosts immune function, improves cardiac health, and increases circulation throughout the body. By helping to control body weight, exercise can lower the risk for diabetes, high blood pressure and strokes.

Pacing is crucial for any exercise routine. Many baby boomers recall their physical education classes from high school, when they had to run around a track, touch their toes, climb the ropes, and work out in ways that later in life might injure more than strengthen. Today’s fitness regimens are varied, and it is often best to sample several exercise techniques to discover what works best for each of us, paying particular attention not just to our health, but also to our enjoyment during workouts.

If someone has an ongoing medical condition, it is best to check with their doctor before starting any exercise program. Also, working out with a friend or group is a great way to get physical and social. You can increase your stamina through mutual encouragement while you chat about other things on your mind, which can reduce stress while it helps pass the time.
