[English Writing] A description of a person

Frankly speaking, he is one of my co-worker in our team. About a year ago, he was somewhat plump.

Actually he was not short, but he did not looks like being in a good shape. He had a big stomach and his chin

 was doubled sometimes. Oneday he suddenly told that he is going to begin to exercise regularly. In the

beginning stage, people didn't expect he could change his body in a short term. However as he does

exercise, eventually there were some changes on his appearance. First of all, something was disappeared

on his chin. He got just one chin he wanted. Second, his stomach and thigh became very thin. So he couldn't

 wear his pants that he used to do anymore. Moreover some people often can't recognized when they look at

 his back. It was an amazing change for others. In other words, it seems like a revolution.

Nowadays he is fully satisfied with his shape and he always recommends doing exercise to colleagues.

If a someone is worrying about his or her shape, I would like to tell them his story that I said. Just do it and

try to keep in shape!
