Karen Marie Knapp's Spiritual Fitness Program for Beginners and the Out-of-Shape:
"Catholic living is very much like weight training: one doesn't start with the big barbell, one starts with the little two-pound handweights and some sit-ups; after some months of work, doing a little more at a time while one's getting strong, one might consider trying the big barbell.
So, I'm going to propose a starter set of spiritual exercises for the out-of-shape, a place to begin...."
Ms. Knapp passed away a few years ago. One can still read her blog here: From the Anchor Hold (" living single, simple, and submitted, in a real city, in a real world. ").
