walkin' the plank (yeah, I said that...)

know what looks simple enough but'll kick your ass so much harder than you could possibly realize?

a plank.  
to be specific, a 45-second plank followed by a 15-second "rest" plank on your knees.  repeated five times.  FIVE.

planks after a tough shoulder workout the previous day?  DEAD.

tomorrow marks phase two of the Best Body Bootcamp, and planks are not on the workout plan.  yet apparently I like pain, since my core, while sore and shredded, feels much stronger, which I can feel in other areas of my body as well.  and with scoliosis, I need all the core strength I can muster, so I'll now be incorporating them into my weekly routine as one of my extra goals.  

so there's that.
