Richard and I have recently added running to our workout regimens - much to my chagrin. I can't knock it too much since it is the fastest way to loose inches, however it's also the fastest way to lose muscle mass (and boobs... can I complain about that for just a second!). To prevent this (the muscle mass loss, not the boobs) we try to include post-workout snacks into our diet. Hard-boiled eggs, peanut butter, and of course, protein shakes and smoothies.
