I Am Not That Fit

One day I visited the gym, and found out that I am not that very fit. 
I was a skater. But not now, so this contributed fat to my body mass.
All my muscles burning fire and aching unbearably.

This makes me wonder how did I manage to stay slim? So much fat in my body.
Many people kept telling me my figure is good.
Yet, I am always unsatisfied. I need to do something before I become fat.

Perfectionist me.

I still love skating afterall. More relaxing than gym. ;D
