Squatting and Deadlifts and Press and Sprints and Sparring(and maybe a Remington 870)
seriously, if you perform those things, you are ready for anything.
You can pick stuff up
You can throw stuff and carry it also
you can carry a human in trouble
you can chase somebody down and take stuff from them
You can run when someone is trying to eat you
You can fend off anything
All you need is a barbell, some weights, a hill to run up and someone to punch and kick. Do 1-2 of these things everyday. Stock up on canned food, Copenhagen, Evan Williams, Water and dog food. Include Cobalt's Gin and Ehg's Take as Needed for Pain and you are all set.
