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?

I would consult his website, but [the forum](https://www.marklauren.com/forum/) seems to perpetually be down.

Do not regret this break from your weightlifting and take the opportunity to become an even better weightlifter.

The trainers I have had, most often has used about half of the workout for yoga exercises to improve flexibility, range, mobility and core strength.
Exercises like over-the-head-squats demands extremely high flexibility.

You can highly improve quality of your squats by doing air squats in front of a mirror.

You can improve your core strength and stability far beyond what you think is possible just by doing functional training and calisthenics - without any equipment.

If you can afford a little for a smaller device, I will definitely recommend you a cheap suspension-trainer aka TRX (cheap ones are as good as the expensive ones), which you easily can attach to a door, and sliding exercises like this: <http://www.6-directions.com/>
You can just use floor-cloths for sliding exercises. I use to do so.

If you dare to try advanced exercises, Switch ball can take your weightlifting to the next level, but I recommends proper instructions.

If you have room for more than that, then get inspiration from crossfit and use sandbags (or water bags), tires, logs, etc. as weights.
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.
