OK, Jerrod, glad you made it on here! You're already doing great on the bodyweight exercises, but I want to set you up with an even better circuit you can use in a round format, resembling the demands of boxing or MMA, to better prepare you for the demands of Doomsday!
You have access to a pull/chin-up bar at home right?
What sort of weights, dumbbells, or other resistance tools do you have access to?
Do you have a sledgehammer and an old tire in the backyard? If not, get it.
