2 . It’s really a challenge for people to find consistent motivation to exercise regularly. Wishing not to hit gyms, you can invent tons of excuses. However, out of most people’s expectation, a certain amount of physical exercise every week can stop your IQ from declining.
IQ, to a large degree, is determined by genes. It has long been established that genes account for about 70 percent of IQ. And environmental factors, like diet, quality of education and brain stimulation, affect the other 30 percent.
IQ can be put into two types — “fluid” and “crystallized” intelligence. The former refers to the ability to reason and think flexibly, while the latter refers to the build-up of knowledge, facts, and skills that are acquired throughout life. The two have a dynamic relationship: fluid IQ decides how much information you can take in and how fast you can take it in, which means a higher fluid IQ contributes to your crystallized IQ. They keep growing until your early twenties, when they both reach the peak. Unfortunately, this will not keep the same for the rest of your life. Fluid intelligence declines rapidly with age.
What causes this decline? It all comes down to your cardiovascular (心血管的) system. It calls for a large amount of oxygen for the brain to function well. The less exercise you have as you get old, the less oxygen your heart provides to supply your brain. Exercise also promotes the release of certain chemicals that are critical to the brain’s health, bringing about better concentration and memory.
Taking proper physical exercise can help to prevent IQ from declining as you get older. Why not choose to hit the gym for the sake of IQ intelligence?

10 . This activity will melt away the pounds, build your body and leave you on an emotional high. Yet the form of exercise, the fitness trend of the year, does not require gym membership or a personal trainer. All you need to do is walk.
"Walking is a refreshing alternative to complicated aerobic （氧）routines and overpriced gym membership," says personal trainer Lucy Knight, author of a new book on the exercise. “It is free, enjoyable and already a part of everyday life. All you need to do is correct your technique, walk faster and for longer and you will lose weight?"
There is much evidence of the benefits of walking. Scientists at the University of Pittsburgh recently discovered that overweight people who walked briskly （快）for 30 to 60 minutes a day lost weight even if they didn't change any other lifestyle habits. Another American study found that people who walked for at least four hours a week gained less weight than couch potatoes as they got older. Researchers at the University of Massachusetts medical school found that people who walked every day had 25 percent fewer colds than those who sat a lot. Best of all, walking makes you feel good about yourself "For people suffering from depression, walking three to four times a week for 30 minutes has been shown to lift their mood,” says Knight.
But how to walk your way to weight loss and wellness? Health experts recommend that we should walk 10,000 steps a day to stay healthy. Actually, you would probably need to walk at least 16,000 steps a day to lose weight. "Your workout plans depend on your level of fitness. You should aim to progress by increasing your walking time by five minutes every two weeks, and walk a bit faster. In just three months, the results should speak for themselves," says Knight.
