Physical Fitness

Physical activity also helps people stay healthy. Exercise strengthens the immune system , and helps the body fight off illness . Daily exercise also helps people sleep better. Active students don’t complain about being tired. They have a good night’s sleep and have the energy to work hard and have fun every day.

  The body is an amazing object; the more you ask of it, the more it can do. If you are inactive most of the time, your body will quickly become tired when it should be active. But if you are active many times each day or week, your body will get used to the hard work and it will become easier to do. Children who want to play active games with their friends should exercise regularly so they have the energy to play as long as they want. 

Many young people want to physically active because it helps them look and feel good. Activity burns more calories than just sitting , so it is important for keeping a healthy weight . Exercise also makes muscles and bones stronger and keeps your body in a good condition .Like the girl and Ronaldo looking in the picture. 

Being strong does not always mean that you have big muscles . Muscle size is often determined by your genes-very few people will look like bodybuilders when they get stronger. Age also helps find out muscle size.Boys may get bigger muscles if they do strength training because their hormones may rise . Girls can also become stronger but they won’t get bigger muscles because their balance of hormones is different from that of males.
