My goal pants

I have selected my goal pants which are the pants that I want to fit when all of this exercising is over.  I admit, they are small, but I want to be that size again.  I've done 5 workouts so far so nothing has changed (except I am sore like you wouldn't believe), but my roommate/personal trainer says my pants will feel looser in 10 more work outs.  I'm motivated!
