I can't say that I am a real sportsman, but I try to keep fit.  I usually don't miss my Physical Education lessons, sometimes do jogging in the park and at home doing the exercises but not every day.  I believe that an athlete may be only tempered person, with strong character and good health. Sport in my life is important but it isn't the most important thing I do, of course.

Я не могу сказать, что я настоящий спортсмен, но я стараюсь держать себя в форме. Я не прогуливаю уроки физкультуры,  иногда бегаю трусцой в парке и дома занимаюсь упражнениями, но не каждый день. Но я считаю, что спортсменом может стать только закаленный человек, с сильным характером и хорошим здоровьем. Спорт в моей жизни занимает важное место, но не самое главное, конечно.
