A theme I always read on other blogs is how to stay motivated in the winter months. It's really cold here, so I'm asking the same question. I believe motivation to exercise starts in the wonderful mind. I have to constantly renew my mind in order not to be discouraged.
Today I plan on start training for my 5K. I'm waiting for the weather to get a little warmer than 27 degrees so I can get out there. Talk about motivation! I thank God for this verse in Romans 12:2:
Do not be conformed to this world (this age), [fashioned after and adapted to its external, superficial customs], but be transformed (changed) by the [entire] renewal of your mind [by its new ideals and its new attitude], so that you may prove [for yourselves] what is the good and acceptable and perfect will of God, even the thing which is good and acceptable and perfect [in His sight for you].
I'm gonna read The Battlefield of the Mind again. Here's an excerpt here.
