My calves are so sore, I can barely walk! But I walked to work, and I'm walking home, so hopefully the lactic acid buildup will be down enough so that I can jump rope again tomorrow.
Update? - I'm still really muscly, with fat on top of it.
Oh, and of course my shoulders and arms are a bit sore from jumping rope, as well.
Edit - oh, and did you know your feet bones and ankle bones can get really sore? Yep, it's true!
