Exercise should (1) be (быть) a regular part of your day, like (2) brushing (чистка) your teeth, eating, and sleeping. It can be (3) working (работа) hard in gym class, joining a sports team, or exercising on your own. Keep our tips in mind:
(4) Find (найди) an activity that you think is fun. Many people find it's more fun to exercise with someone else, so see if you can find a friend or family member to be active with you. Take it one step at a time. For example, (6) walk (ходи пешком) or (7) ride (езди на велике) your bike to school or to a friend's house.
Use the stairs more often. In addition to exercise, (8) making (делая, хотя тут герундий играет роль подлежащего, как существительное) just a few other changes in your life can help keep you healthy.
Either watch less TV or spend less time on (9) playing (на игру) computer games. (Use this time to exercise!) Eat 3-5 healthy meals a day, (10) drink (пей) enough water before, during, and after any exercise. Stop (11) drinking (после глагола stop в значении "прекратить" всегда используется герундий) or drink fewer soft drinks.
