Until quarantine（隔离期）ends,we are left picturing what sport we might do：working out at the gym,playing on a competitive sports team,swimming,biking,or rock climbing.However,we don't often think of martial arts as possible activities；instead,we rule it out because we think it's dangerous,uncommon,and even,impossible.Martial arts aren't considered a sport,right？
Well,here's some good news：you're wrong!Martial arts aren't much more common than people think,and you can start learning at any age.Practicing martial arts is a great way to keep in shape,both physically and mentally.They're much less boring and much less arduous sport than they're usually described as in movies,so do not worry that they need a lot of effort.
Martial arts generally require you to focus on the position and movement of every one of your legs and arms,sometimes even your breathing too.Think about it：when you leave the gym,your mental state has improved and you are much calmer.This is because you've only paid attention to one activity.It is a great way to clear your head.And practicing it can help you learn to stay more focused,which is the greatest advantage of martial arts training.
Martial arts also improve your coordination（协调性），and greatly improve your posture（姿势）.I have personally seen students go from slouching（没精打采）to walking tall with their shoulders back in just a couple of months.
There are many styles and countless kinds of martial arts.Whichever one you like better,know that all of them are good choices.
