I strongly agree with the idea: “physical exercises are very useful to our health” for the following reasons. First of all, physical exercises make us stronger. Last year, I used to be very weak, my teacher advised me to exercise more and now I am much taller and stronger than many other friends. Furthermore, physical exercises help us have a nice body and keep fit. For example, my mother used to be overweight but now she is as slim as a Miss. Everyone wonders what makes her become slim like that and the answer is her doing physical exercises regularly. Last but not least, physical exercises help us relax very much. Exercises not only give us encouragement to begin a new day but also help us refesh ourselves after a hard-working day. In conclusion, It is necessary that we do physical exercises
