What I am going to do, though, is get home, put on the rest of my exercise clothes, and walk out the door. (See, I'm wearing a sports bra and workout tank top under my long sleeved shirt, so all I need to do is swap my jeans and shoes for their running equivalents and I'll be nearly ready to go.) Once I actually get going down the road, I'll be better able to judge what my body is capable of doing this afternoon.
I realized about 45 minutes after lunch just how well fiber can contribute to a feeling of fullness. Lunch today was half a sweet potato topped with about a cup of black-eyed peas, plus a mandarin. While it was of reasonable theoretical volume, in my belly it felt like I would never need to eat again. :) Of course, as that was nearly four hours ago, I am, in fact, a little bit hungry right now, but that's just my own personal need to eat every 3-4 hours.
How about you--when you're not sure whether you're up to exercising, how do you approach the dilemma?
