That was a great read about cardio before lifting. I have tried both methods and havent felt or seen a difference. What works best for me is not to get in a set routine for cardio as far as time of day, on empty/full stomach and type of cardio exercise. I do stick to the same time period and get my heart rate to the same levels. I have noticed a minor difference since adapting this method about 2 years ago. I am probably wrong but I feel that this method helps my metabolism reep better benefits of the cardio.
