"If training is always your number 1 priority, something is seriously wrong in your life."
This is some great wisdom - remember it.
That being said - when shit gets crazy for me - I have two things I do. The first is I shift to "jack shit" 5/3/1 (you don't hear about this match anymore but if you pound your last set and/or do some fsl - you will make great progress. I'll throw in some abs/ low back but that's it.
Or, will scale down to just conditioning. I have done this for upwards of three weeks at a time with no lifting and then been able to start back up where I left off with virtually no strength loss. The benefit to this is that I own a sled and a weighted vest - so I do not have to drive to the gym. I do these things with virtually no transportation time necessary. The best though, is I am fortunate enough to live near a HUGE, steep, hill.
Find one and run up it a lot. You will be amazed how long you can go without squatting and still make gains - I kid you not.
