I don't do alot of cardio. I mostly do cardio in between if I am not going to be wrestling for a few days. For the most part, cardio for me is if I'm going to be wrestling that night. I'm going to probably go 20 minutes or a half an hour, very intense cardiovascular stuff, so I don't need to do it earlier in the day.
I usually take my major body parts, like my chest, and do maybe four exercises. And I usually do three sets per exercise. And I almost do each set to failure - when my body won't let me do another rep. With my major body parts I'll pick four exercises and do three sets per exercise.
On smaller body parts, like biceps and triceps, I might do three exercises. Three for shoulders as well and probably four for the legs.
