Just spent a four day weekend in Paris, France. Although I didn't have an opportunity to hit a real gym, I walked several miles a day and carried a 50-60 lbs stroller (weight includes the baby!) up and down steps the entire trip. The Metro and RER trains in Paris are not stroller friendly, so it was a pretty solid daily workout. Back at it this week, with a much better diet than what I was eating in France, and more gym-oriented training!
