If our bodies are for the Lord, does it matter if I exercise?

Given what Paul argues in 1 Corinthians 6 about the importance of our bodies and their role as temples of the Holy Spirit, it follows that what we do with and to our bodies matters. In light of that I found this discussion about exercise, sleep, and diet especially interesting. What sort of impact can the way we treat our body have on our sanctification? Is exercise a spiritual discipline?

Watch and let me know what you think.
