contrary to what most think, your dick doesn't fall off when you take a one or two week vacation from training.
All jokes aside, you should maintain a few things in your "off" weeks like running or sprinting, long jumps or box jumps if you can MacGyver something to jump on, pushups, bodyweight squats, and chin-ups if you can find a place to do them. Pack a jump rope too and use it for some conditioning if you don't want to run around outside.
When you get back, just start off on week 6 or 7 and push forward. You might even come back stronger with the time off and a couple weeks of a conditioning focus.
