I talked about how plants need good soil and the right conditions to flourish, look good and bear fruit. We humans also need good soil and the right conditions to live well and flourish. We looked at enriching our soil by eating the right foods but that is not enough by itself. We can improve the soil even further with exercise. In societies where people are healthy and livelong lives exercise was an integral part of what they did everyday, it was a side benefit of what they did to meet their basic need. They didn’t have a particular exercise program and nor did they need special equipment; they just moved their bodies for most of the day. Studies have consistently shown moving our bodies and exercising is associated with not only good health but longevity. In our society we tend to think of exercise as work, it is much better and more likely to be done regularly if it is a by-product of something you enjoy doing or as part of work routine. It could be gardening, biking, swimming, hiking, skating, cross-country skiing or anything else you might enjoy as long as it gets you moving most of the day. I myself try to keep moving by taking the stairs in the hospital instead of the elevator, park my car further away as possible from the store and my job also requires me to keep moving by having to go to see patients from one room to another in my office and in the hospital. Part of my activity to be on my feet is intentional and part of it is built into my job. I augment my bodies movements by cross-country skiing in the winter and hiking in the summer because I enjoy these activities. The main physical benefits of exercise include increases in strength in muscles, bone, ligaments, and tendons; endurance; flexibility; and balance. Side benefits include weight control, improvements in the serum lipid profile (exercise raises HDL cholesterol), and reduction in blood pressure. Exercise can also reverse and possibly prevent type-2 diabetes. Exercise stimulates brain cells and tends to make people more relaxed. It creates opportunities for social connections and for connection with nature. In addition, exercise increases the muscle-to-fat ratio…[and weight-bearing exercises strengthen your bones]. Exercise is absolutely the single most consistent factor in staving off cognitive decline that occurs with aging. …Professor Anthony A. Goodman, Montana State University If you haven’t been exercising where should you begin? If you haven’t been active at all and you should start slow. You may even want to talk to your doctor before starting . Good indicators of fitness level can be your resting pulse rate, average is about 70. The other indicator is the recovery time. You exercise to 80 percent of maximum heart rate for your age and then see how long it takes to return to under 100. With low-level of fitness the longer it will take to recover. You can monitor your fitness improvement with this measurement over time. The maximum heart rate can be calculated by subtracting your age from 220. You can get more details on the recovery time on these sites :-
Set realistic goals. Consider your work schedule and other commitments you have. The aim is to move as much as possible everyday and then, at least three days a week, include some strenuous activity that gets your heart rate up and gets you sweating. During aerobic exercise, aim for about 80 percent of the maximum heart rate for you age group. In general, avoid training hard more than three times a week or every other day. Exercise and may you live long and with vitality.
