You are not very thin and you are not fit?
How come?
Being you not verythin means that you'r fit,right?

You can be fit and heavy but a lot depends on your over all health.
Most over weight people are not healthy, as well as some thin people are not healthy either

So fit it's not about skiiny or fat it's about being healthy?

I think so. But many people will claim they are healthy and aren't so I think it depends on what you call healthy. Like what does the doctor say? Can you exercise without getting out of breath and worn out?
Things like that.
