In case you're curious, I'm regularly switching cardio activities and intensity because I'm trying to keep my metabolism guessing, and therefore keep burning fat. I've learned my body quickly adjusts to doing repeated routines and fat loss gets steadily harder unless I switch things up fairly often. Seems I'm just one of those people whose body can find a way to store fat even while actually running in a marathon apparently.
I'm also regularly switching Core activities because I'm not really trying to "progress" with them. I want to hit them different ways because I think that will make them stronger overall. That's my theory anyway.
Well, that and mentally I do like doing a variety of different things too and this is a way to get some variety since my workout is pretty repetitive.
