I wondered what happened to you! Have you begun your big OE???
Someone said something about how they don't take days off because if they take days off they get injured. I'm definitely like that. If I don't do my mobility work every single day my body starts to seize up. miss a day and i need to spend 2x as long the next day for 1/2 the effect.
You got a foam roller?? Dare I say gently does it??
Push-ups, pull-ups, unweighted squats (or you gotta have something you can hold or put on your back. your wife or something), lunges, one legged squats... Probably just moving around would help.
Didn't someone tell you to pack a barbell for your trip??
