Culture sport and fitnesssport and fitnessThe British like sport very much, but many people prefer to watch rather than take part. Many go to watch football, rugby, cricket, etc. at the ground, but many more sit at home and watch sport on television.Most people today take relatively little general exercise. Over the last 30 or 40 years lifestyles have changed considerably and many people now travel even the shortest distances by car or bus. Lack of exercise combined with eating too much fat and sugar has meant that many people are becoming too fat. Experts are particularly concerned that children spend a lot of their free time watching television or playing computer games instead of being active. In recent years, however, there has been a growing interest in fitness among young adults and many belong to a sports club or gym.In Britain most towns have an amateur football and cricket team, and people also have opportunities to play sports such as tennis and golf. Older people may play bowls. Some people go regularly to a sports centre or leisure centre where there are facilities for playing badminton and squash, and also a swimming pool. Many sports centres arrange classes in activities such as aerobics(= exercises to music), step(= stepping on and off a low step)Spinning™(= exercise on a bike), Zumba™(= dance based exercise) and keep-fit. Some people work out(= train hard) regularly at a local gym and do weight training(= lifting weights to make their muscles stronger) and circuit training(= a series of exercises that use a lot of energy). Some people do judo or other martial arts(= fighting sports). Others go running or jogging(= running at a slow pace) in their local area or on a treadmill at the gym. For enthusiastic runners there are opportunities to take part in long-distance runs, such as the London marathon. Other people keep themselves fit by walking or cycling. Many people go abroad on a skiing holiday each year and there are several dry slopes and snow domes in Britain where they can practise.Membership of a sports club or gym can be expensive and not everyone can afford it. Local sports centres are generally cheaper. Evening classes are also cheap and offer a wide variety of fitness activities ranging from yoga and Pilates to jazz dancing. Some companies now provide sports facilities for their employees or contribute to the cost of joining a gym.Sports play an important part in American life. Professional baseball and football games attract large crowds, and many people watch games on television. Although many parents complain about their children being couch potatoes(= people who spend a lot of time watching television), there are sports sessions at school for all ages. College students are usually also required to take physical education classes to complete their studies.Many popular keep-fit activities began in the US. Charles Atlas, Arnold Schwarzenegger and others inspired people to take up bodybuilding(= shaping the muscles and making them strong). Some richer people employ their own personal trainer, either at home or at a fitness centre, to direct their exercise programme. But many people just walk or jog in the local park or play informal games of baseball or football.
