I started feeling better later in the evening. Woke up at 4:00 and made the decision *not* to go to boot camp, though. I still feel "off," but so does DH and it's not the skiing. Most of my muscles are fine, now, just my usual lower back and right hip. My stomach is a bit weird and I'm itchy, which means some kind of allergy reaction, probably to all the eating I did up in NH!
I did do a little warm up on the treadmill and then a 15 minute core workout on the ball in my home gym. There's going to be a lot of snow sports over the next month, with the amount of snow we are expecting. I may take the whole week off from the gym, and concentrate on being outside. I can do some weight and core stuff at home. My weight is up 3 lbs. from the trip, and I feel very flabby. Time to tighten up a little, although this kinds of things usually resolve themselves in a couple of days.
