Great responces...
So depending upon how serious or casual an athlete you are, the proper ratio and qualtity should be discovered via a normal trail--error--correction--solution process.
I suppose it is safe to say that whatever the body does not need for recovery can be stored and used later. Being fit and working out regularly would prevent the set of problems that could arise from excess. Also, being athletes we have a pretty good sense of what "feels" right...so, go with your gut...(sorry, just had to).
Thanks!
