Physicians and scientists have often called the human body a beautiful instrument. The sense in which this metaphor is applied is primarily mechanistic. The human body is a beautiful instrument in that its parts mesh properly and each component performs its function superbly. The metaphor "beautiful

What's your worldview? Are you an optimist or a pessimist by nature? Do you always expect good things to happen or are you waiting for the other shoe to drop? Our mental attitude affects how we interact with others and how we respond to events and the comings and goings in our daily lives. Remarkably,

For thousands of years, humanity has struggled to understand the place of men and women in the universe. All sorts of explanations have been brought forward, many proposing that humanity is part of a greater whole and helps contribute to the welfare of all. Equally many theories suggest that humanity

Renewability, sustainability, and energy conservation are all over the news. Every newspaper's front page and every television nightly news program features sustainability daily. These are important issues, not only for the health of our planet, but also for our physical health and well-being. Our physical

Back in the day, there were no personal trainers. If you needed to learn how to exercise, you got a subscription to one of a few well-known "muscle magazines" and read several issues from cover to cover. Then you joined a "Y" and began to discreetly observe what was going in the weight room, trying to

Not everyone will admit this, but there's something magical about exercise. Your brain produces endorphins in response to vigorous exercise and you feel energized, alert, and alive.

Mao Asada, Silver Medalist in Ladies Figure Skating at the 2010 Winter Olympics, landed three triple axels in the competition, a feat no competitor had done before. There are no easy figure skating jumps, spins, or technical elements, but the triple axel is particularly difficult. This jump has many

If a great Shakespearean protagonist had, anachronistically, joined a gym, his internal existential inquiry might have been, "To lift or not to lift?". Many centuries later, the identical inquiry, or controversy, persists. Joining a gym (health club) usually implies the new club member is going to engage

Cross-training refers to a combination of different methods of exercise. Specifically, cross-training refers to the combination of strength training and cardiovascular training in your overall exercise program.

Strength training, otherwise known as weight training, is one of those activities that provides a wide range of benefits for the person who does it regularly. Like yoga, strength straining makes all your muscles stronger, enhances flexibility, and improves cardiovascular capability and capacity. In fact,

Interval training is an important part of aerobic exercise. If you're a walker or a runner, run intervals once a week. Walking and running build endurance by strengthening your cardiovascular system. Doing interval training once a week enhances your endurance by dramatically increasing the amount of

"To stretch or not to stretch." That wasn't exactly Hamlet's question. The Prince of Denmark had matters of state to consider, especially the most effective method to avenge the murder of his father. Getting ready for his next fencing lesson had taken low priority. But for the rest of us who aren't

Here comes summer! Fun in the sun. Barbecues, fireworks, and cool drinks. And outdoor activities - hiking, biking, running, swimming, skating, blading, and even canoeing. Getting back into shape seems like a very good idea right about now. We want to look good in our shorts and tee shirts, and more

We all want to get the most out of the time we spend exercising, and it's natural to think that exercising harder is going to provide a bigger, faster payoff. But exercising harder without adequate preparation often leads to injury. Then there's recovery time, possibly the need for rehabilitation, and

As Martha and the Vandellas sang back in the 1960s, summer's here! There's so much to do and we want to make sure we have a great time. Baseball, basketball, volleyball. Swimming and surfing. Walking and running. Hiking and climbing. Rollerblading and skateboarding. Now that summer's here, everything's

Climbing a hill is a useful metaphor for activities involved in accomplishing a major goal, overcoming longstanding obstacles, or achieving a noteworthy milestone. But you must be prepared to engage in such a climb. Striking out without a metaphorical map, compass, bottle of water, or raingear will consistently

It seems as if every few months there’s a new diet whose rules and requirements we must follow if we’re going to reach the goal of good health. The “paleo” diet provides a great example of this phenomenon. We’re exhorted by paleo proponents to eat lots of fats and animal protein. Carbohydrate

We think mostly of chiropractic treatment in terms of lower back pain, neck pain, and headaches. In fact, there are numerous additional wide-ranging benefits to chiropractic health care.

Ever notice how strength training and aerobic exercise go together? Aerobic exercise accentuates strength training because you have more endurance. Strength training makes aerobic exercise better, more fun, because you have more power. Like marshmallows and campfires or vanilla ice cream and hot apple

We're all familiar with the mechanism of action-and-reaction in the world of sports. Pitcher-and-batter is an action-reaction duo in baseball. A basketball guard driving to the hoop and a defender leaping to block the shot is another example. A racecar driver negotiating a tight turn at speed is executing

Chronic diseases such as hypertension and diabetes have increasingly high prevalence in world populations.1 Such prevalence is rising despite extensive use of prescription medications.

Approximately 23 million Americans suffer from migraines. Billions of dollars are spent each year on Aleve and Motrin

Many of us think of depression as a psychological condition. The causes of depression are sought in the person's childhood or in her personal circumstances as an adult. But within the last 10 or 20 years depression is increasingly being evaluated within a physiological context. Various disease states

We all want to get the most we can out of life. Whether we want to find a loving partner, work at a meaningful career, gather an abundance of financial resources, or have enough leisure time to pursue favored interests, the usual bottom line is that we want to be happy. Throughout thousands of years

Cancer is a health issue for many families. It's important to understand that there are different kinds of cancers. Not all cancers are life-threatening. Some types may be very serious and some may be dealt with relatively easily. First, it's important to distinguish between benign and malignant tumors.

We all know someone with high blood pressure (HBP), possibly a beloved family member or a lifelong friend. This common problem affects one in four American adults.1 An alarming 75% of patients with type 2 diabetes also have HBP.2 High blood pressure is particularly dangerous because, for the most part,

As we get older, years and decades of mechanical stress may lead to deterioration of joints, ligaments, and tendons. This degenerative process, commonly known as arthritis, primarily affects weight-bearing joints such as the hips and knees and those found in the lumbar spine. The shoulder, too, is especially

Chronic knee pain is notoriously difficult to treat successfully. Persons with these problems often become discouraged as they shuttle from specialist to specialist, from rheumatologist to orthopedic surgeon to physical therapist to acupuncturist and back again. Lack of progress and improvement becomes

The condition of fibromyalgia creates many challenges for a person with this disorder. These challenges often go far beyond the characteristic chronic pain which alone can be potentially debilitating.
