to be honest, this does relieve some of the pressure

I'm not saying we don't need to tend to the bodies with which we were gifted, but anything can turn into an idol, even Exercise. 

From the Baltimore Catechism:
Q. Of which must we take more care, our soul or our body?
A. We must take more care of our soul than of our body.
Q. Why must we take more care of our soul than of our body.
A. We must take more care of our soul than of our body, because in losing our soul we lose God and everlasting happiness.
