Answer:
I have a question which I will answer so don't worry. Have you ever stretched before running, jogging, in general, do you do yoga?
Explanation:
So Stretching before you do something helps warm up your muscles, it also helps your body know to know what muscles are probably going to be used. I know in my Karate class the first thing we do is stretch jog in place, and just kind of warm up before we start throwing punches and kicks. If we didn't warm up we wouldn't be able to give it our best because our muscles would be too tight so. And also Yoga is something I have recently taken up and it is like exercise for me and all I do is stretch the whole time. I did dance for 7 years and can fold in half and wrap my arms around my knees just by practicing it everyday. so if you stretch a little at a time you'll feel loads better when you are done.
