So I’m moving on Friday and I got the keys to my new apartment last night.  I brought some kitchen items with me, and made 7 trips up and down 3 flights of stairs.  Can we say my ENTIRE body is SORE!  My knee was tired last night after it all - but today feels ok.  The muscles in my arms and legs on the other hand are TIRED and don’t want to move!  Looking forward to many more trips up and down the stairs this week - go stair master! :/
