Exercise is good for our mind and body.Today，exercise through online videos is becoming very popular.Since the Internet is widely used，it's very easy for us to do so.That means we can exercise anytime anywhere.
   One of my friends，Lin Fei followed short videos to do daily exercise. "With the videos，I feel like exercising with my friends，which encourages （鼓勵） me to keep moving." she said.Another friend of mine，Michael，told my that videos let him feel so comfortable. "I have a fear of exercising at the gym （健身房） because I'm shy and I don't like being watched by others.Exercising at home makes me feel much more enjoyable." he said.
    With their examples，I decided to give it a try.When I told my plan to my elder sister，a P.E.teacher，she reminded me that videos could be helpful but might still carry some problems.
   "Without being with someone，you won't be hard-working.Exercising at the gym allows you to have advice in real time and work hard." my sister said to me. "Well，if you really want to have a try.First，choose right programs or videos.That's very important.And then ask your friends for advice."
   At her suggestions，I finally followed an online program.After the first period （時期） of training，I felt it very helpful when I put in the right amount （量） of work along with a strong will.Compared with going to the gym，using online videos to exercise is a much cheaper and time-saving choice.But it can be difficult sometimes when I'm too lazy or too busy to keep it.
