Very true.  Being skinny doesn't feel all that great (though I am a dude, maybe it does feel awesome to women).    Being fit does feel awesome.  Being able to say "I've got 60 seconds to make it to my class and 3 flights of stairs, no problem!"  Or "couch needs to be moved?  I got it covered" is an outstanding feeling.  I make outstanding brownies but no brownie tastes as good as lifting a couch by yourself.
