How to stay fit in middle school
Get moving.
Doctors advise that middle schoolers get at least an hour of physical activity every day: that's 60 minutes of moderate aerobic activity like walking or intense activity like running. Regular exercise will give you stronger bones and better skin, help you keep a stable weight, and give you mental and mood boosts.
Do things you enjoy! Exercise doesn't have to be a chore. Do you like to rollerblade, play basketball, dance, or ride your bike? These are all great-and fun-physical activities.
