I actually did this when I quit-- I started playing guitar again after 30 years away, and I also joined a Crossfit and lost 40 pounds and got very fit.
Working out and a creative outlet were a great combo.
I added Yoga to the mix to get some body awareness and that really made it work--you carry a lot of "old" emotions in your body tension that it feels good to release, strangely enough.
Keep us posted CR!
