we definitely have a big range of ideas what a cardio session is. Mine is usually 5k on the thread mill in 30mins and that totally knocks me out for the rest of the day. Simply dont have the fitness to do cardio and weights in the same day anymore. Used to be able to do weights then go swimming but thats another story.

8-10 minute jog is more like warming up rather than a 'cardio' in my book =P
