Emergency Gym Opus

The other day as watched the 4th episod of an anime the same as any other anime with just the difference of a robot with a scottish flare, 'Heat Guy J' i then had the sudden urge to work out.
Now, for those of you who havent seen/known me, i was once in shape. Now, this pudgy physic and round jolly attitude i then realize that i am comfortable. I am comfortable with the way i am. Is this Bad? Does that mean that i no longer want to better myself?
the sudden urge to work out increased to a point that i've started my training again.
So far i realized that i'm a lot slower, and heavier on my strikes, and my endurance is shot.
I must logicaly see the need to continue this Work Out feel, cuz i dont want to do it like anyone els flopping about the local 24 hour fitness hole, all with bad self esteem, and seceretly hate themselves. I want to do this cuz its healthy, improve my skills in the martial arts, and for the fun of it.
now if only i can believe my own words......
