M: Right. What about the second type?
W: The second type is endurance exercise. That trains the heart, lungs, and muscles to work hard for a longer time. Thus, while regular 20 minutes’ walks may help you live longer, regular one-hour walks can help you play longer.(6)The third type is strength training, which builds muscles. The improvement is little felt and fleeting at first, but regular use of the same muscles eventually increases their size and strength.
M: You mean like those body-builders who have got enormous and beautiful muscles?
W: Not exactly. Strength training isn’t just for the vain: having stronger back and abdominal muscles, for example, supports your spine, making back trouble less likely.
M: I see.
W:(7)The fourth type is flexibility exercise, which keeps muscles long and supple, so they’re less likely to be injured.
M: Do we have to engage in all those forms of exercise in order to stay in shape?
W:(8)Not necessarily. It all depends on your need, and also age, younger people could engage in more vigorous activities or deliberate workouts, while the older people could just try anything that burns a little more calories, like walking or even gardening.(9)The word " exercise" can be quite loosely defined. It can include out-of-the-gym activities, such as lawn-moving, leaf-raking or even cleaning the house. Just about any amount of physical activity will improve fitness.
M: Then when should one begin? Say someone has been inactive for years, is it too late or is he too old to exercise? Could he change his way of living by working out a little right away?
W: Absolutely.(10)One could get started at any time, any age. The greatest benefit of exercise may come at the beginning, when you jump from doing nothing to doing something. At the beginning, you just try a little. Walk a few more steps: every day, park the car a few blocks from work. Don’t use an elevator when you can walk. Don’t use the phone to ask colleagues questions: walk to their offices. At home, don’t use the car for nearby errands. Walking the dog, playing catch with the kids, gardening, mall-walking all count as exercise.
