the one of sometings which I love - 2

I love to go to the gym at the U of C about two or three times a week. I like to feel pain in my body after I work out.
When I was a child, I was very weak. I had weak eyes and a thin body like a chopstick. Whenever the seasons changed, I caught a cold. Furthermore, I had to work sitting at my desk all day long. Finally, I got a pain in my waist which made me very stiff.
I had to do something about my health. First of all, I quit smoking. I had been smoking about 2 packs of cigarettes a day since I started to smoke 11 years ago.

Then I got a personal trainer to help me train correctly. It was very expensive but I invested in my self-improvement. However, it was not easy for me because I had to work 13 hours a day so I had no time.
Nowadays I am so happy in Calgary because I can get enough time to exercise for my health and I feel much better than before. I can't find my big beer belly which I had before.

Moreover, I can help my friends to correctly exercise like my trainer taught me. I enjoy helping my friends work out in the gym. I know the most important things are the order of exercising, the methods of breathing and using the equipment. If someone doesn't know the order, he or she could get hurt.
I don't want my body to look like a professional. I just want to keep my good health. So who is he in the picture? Me? Absolutely not. (ㅡ.ㅡ;;) Actually I don't know whose body is in the picture, but I know if I want to make my body look like the picture, I would have to stop eating all delicious foods and eat only chicken breasts, protein drugs and energy bars and I don't want to do that.
