High five bro.
You came off pretty excited, that's good. You also gave some common sense unlike a "few" others

Check out the WOD (Workout Of the Day) on the main page. This is great start, but you may want to ask one of the more "conditioning-inclined" members for a custom workout.
I did pushups, lunges, squats, dragon flags, raise-the-roof, and some dumbbell lifts. (30, 60, 70, 20, 30/12 respectively)
Also, do lots of sprints and tabata's. Browse around

And don't go on roofs, or the APK Roof Police will put a cap in you! (LoL, JK!! Maybe
