Ernest announced yesterday, "I'm out of shape. I've lost all my lung power."
During the last school year, due to the weird scheduling of his math class, he had P.E. 4 days a week (twice with the 6th grade, twice with the 7th). He loved it. At the beginning of the summer he rode his bike a lot. Then he was away for 2 weeks, and spent 3 more weeks at the zoo . Not much bike riding.
So now he has a get-in-shape plan: ride to the river and back twice a day.
