The description in the book describes touching the right hand in front of the left foot while the right leg goes up, then says to repeat it with the left hand going down, and that you've completed one rep when you've done that. Then, it says to switch legs. So, when doing ladders (1 rep, then 2 reps, then 3 reps, etc), is one to do the right leg twice as one rep, then do left twice, right twice as the second two reps, and so on? Or is "one rep" supposed to be twice on the right and twice on the left?

Training is in essence applying force to a resistance. How that resistance looks like is just limited to your imagination.

* The World is your gym (phrase stolen from Ross Enamait)
go out and train outside in fresh air, you can do pull-ups, chin-ups, dips on trees or monkey bars on playgrounds, using heavy stones, barrels or kegs for overhead lifting or deadlifts or big logs.
Running up hills for conditioning is an challenging task... too.
* You are your own Gym (phrase stolen from a title of a bodyweight training program od a farmer navy seal - Mark Lauren) you can do bodyweight exercises in addition or just alone, there are some outstanding programs outhere. I recommend: Never Gymless-Ross Enamait, YAYOG - Mark Lauren or Convict Conditioning by Paul Wade.
* Make your own gym:
Depending on your Budget and available space for training you could build some of the tools on your own, here is some Information on custom created tools like bulgarian bags, sandbags, gymnastic rings, trx bands and kettle-dumbells.

now go do something...
Lifting>family

but really, you might be able to find a place to do chinups in a park or on a tree or something, it's one of the best exercises to do. Maybe you can buy a metal bar from a hardware store and make a chinup station yourself. Dips are also great. Other than that you can start a running routine.
