While the Bible tells us our body is a temple (and therefore we should treat it with respect), only training to be fit means nothing to the Lord! We must work harder to be fit in our relationship with God, than our earthly body.
"But those who trust in the Lord for help will find their strength renewed. They will rise on wings like eagles; they will run and not get weary; they will walk and not grow weak." Isaiah My favorite verse
i hate the worry, i don't want to be model skinny but i want to feel comfortable, other skinny woman's bodies dont motivate me because thats not how MY body is. MY body will always be different than a models.
