How much time should an average to advanced fitness level individual spend on cardiovascular conditioning?

I tend to try for an Hour a day. I like to do my cardio in the morning before I eat then eat a high protein and carb breakfast. The later that day to my weightlifting. If you are doing weightlifting do it after running. Running after lifting weights can ruin your workout. Then you should always eat protein after your workout. If your in a rush, tuna n water, canned chicken in water, peanut butter and jelly. chocolate milk, protein shakes, protein bars are all good options. Another thing you can do for running is instead of seeing how long track how many miles and try to improve your miles weekly so start with 1 mile or so depending on how fit you are right now and work into doing more and more as you go. I hope this helped.
