Gym class

Boo is in a very competitive and fun gym class every Friday. The teacher wants everyone to do 40 sit ups for class next week. I thought he meant per day although one parent laughingly corrected me b/c it is 40 for the week. Hmmm....should I correct Boo? I mean really if Brittney Spears could do 400+ daily pre Sean Preston why can't Boo do 40 at age 6???

These are my ponderings at homeschool gym...other mothers discuss Latin curriculums....I muse making my son's abs muscle stronger...do I need help???
