He hates physical activity, and he especially hates gym class at his New Brunswick school. If the kids on his team in gym tease him for being overweight, he goes out of his way to make sure they lose.

But when his friend Amy suffers a dangerous attack of asthma, Toby is forced to look at exercise in a different light.
