food-come on bro,I know times are hard,but eggs and milk is cheap,or find a health store that has some protein going cheap.
I don't care if it's godamn soy protein,neck it down.it's calories protein and fibre.
In fact,you can usually get dehydrated soya chunks for like $3-you add water and it swells up to 2/3 times it's original size,so a half-pound bag becomes 1.5 lbs. it stays fresh.add soy sauce,any veg you can get,and ramen noodles-dirt cheap.
you could go commando-I don't mean take your underpants off-army style eating?
look up some bushcraft sites?-can you shoot/trap rabbits/pigeons with a catapult or something?
worm omelettes? roadkill? try and run something over in the car?
buy a cheap fishing rod? or a castnet?
pick berries? dig up roots?
If you're driving cross country a lot,farmers usually have some extra eggs/milk,etc. they sell direct at the roadside,or ask them-strike up a deal-you milk the cows,you keep a gallon of raw milk-potent stuff!!
training wise-here ya go-
the MacGyver workout-
find a park/playground with monkey bars/jungle gym.
This might sound crazy,but I believe you may actually benefit from a break from weight training,and doing some bodyweight training,apparently it recruits more of your CNS (Central Nervous System) and sharpens your mind-muscle connection.
I train clients with little or no equipment,or improvise and work with with what they have or can afford.
It doesn't need to be a gym or shiny set of weights.
A weight is anything you want it to be-a suitcase,a gallon jug of water-these are great because they have a handle,but anything will do.pushups are great-lots of variations-put something on your back if you want more weightt-a beam or sturdy doorway is a chin-up/pull-up bar.dips can be done anywhere.a large bag of rice is a medicine ball in the right hands.
Find a scrap yard or construction site if you can,that will let you root about,and give you stuff for free or a few bucks.borrow a sledgehammer,whack the shit out of an old tyre.grab an axe and split wood.volunteer to help out with any menial job for an hour-mopping out,washing dishes,etc. at a diner or anywhere in return for lunch.
Concrete blocks are weights.as are logs,etc. ropes or bungees/harnesses can be used to climb up or a pulley system set up for lat pulldowns,etc. or use as 'blast straps' or for inverted rows,etc.-check out the TRX suspension system for inspiration,or olympic gymnast training.
Sandbags are a great tool,you can get a gruelling workout,and they usually run about $10 or less,and you can stick it in the trunk for the future.
flip some tractor tyres.get out and push the car for a bit...
old school training (a lot of improvisation,including sandbags)-
the possibilities are endless...
The only limit is your imagination!
when your tour is over,get back to us with a new post!! photos if you can!!
