Let me start by saying that I am by no means in shape. And from what I can tell there are alot of musicians who aren't in shape either. I know organists who when they get on the organ, thier stomach is touching the organ.
About a year and a half ago God had elevated me to play at a pretty big church. But with this elevation, I was required to be at the church 5 days out of the week, for rehearsals, which could last for hours, and other things that go on. So between work and church, my eating habits got horrible. Going to fast food places on my way to rehearsal and then right back after rehearsals and not to mention the dinners that would be cooked when we had to sing at other churches.
Between work and the church there was no time for the gym, or excercising or trying to eat right. And after talking to a few of my musician friends they feel the same way. For most musicians, music is life, So a majority of our time is spent doing something music related, so we don't think about that stuff. I was gaining weight and didin't even notice until my Pastor preached "being healthy" to us.
I'm not trying to be funny, I just wanted to share that, because I know I'm not the only one who gets so caught up in music that when I get hungry, theres only time for a $1 Double cheeseburger, then its off to play. I think we really got to get a hold on this because I want to be here to see my kids play (when I have them), and thier kids play for a long time to come!
