Who's got a potbelly? (Oh sorry--was that not the "politically correct" term? *gagging*)
I figured out the solution to all our "old people" woes. GO PLAY WITH SOME KIDS! For the last 2 years I've been trying to kick that constant baby belly by running. Granted, it feels great and I've gotten the results, but after playing "Tag" and "Mother May I" and "Hide and Go Seek" with my kids for 1/2 hr, wow! FULL BODY WORK OUT. Who needs running--boring, grueling, tiresome, tedious running? Hit the park and adopt a toddler for an hour.
...but don't take him home. That could be bad. I mean, for you.
This is my usual form of exercise. And yes, that's the playroom after 1 hr of cleaning.
