MY DAD RIDES A BIKE IN HIS BEDROOM.

My dad rides a bike in his bedroom. He rides, but he never goes anywhere. Isn't that funny?

When I ride my bike, I pick up Jordan at home, and we go all the way to the park. We go everywhere.

My dad gets up at 6:00 A.M. to jog around the neighborhood. He always huffs and puffs and lies down on the kitchen floor when he gets back.

I run, but not like that. Jordan and I race each other home after school. Sometimes I have to chase my dog, Hercules, all over the neighborhood.

My mom has this step thing. She bought it to get in shape. She steps on and off it about fifty times in a row. To me, it looks boring.

Jordan and I built this cool tree-house in my backyard. We have to climb up the tree to get in it. We always forget stuff to take with us, so we climb up and down the tree a lot. I tried to get Mom to climb up there. She said, "I'd better not--I'm out of shape."

Mom and Dad belong to a health club. They lift weights and grunt and groan.

Once I tried to carry Hercules up to the treehouse. Mom caught me and told me not to.

Mom and Dad always tell me to keep my body in good shape. I like feeling strong and healthy. But I don't lift weights or jog or do a step program.

I asked them about starting my own exercise program. Dad said, "Kevin, your whole day is like an exercise program. You get a lot of exercise. You don't think about it because you're having fun. Maybe your mom and I can learn from you."

My dad still rides the bike in his bedroom. I ride it sometimes.

He rides a lot more with Jordan and me.

Mom climbs up to our treehouse now and then. She always asks if it's OK first. We let her come if she brings a snack.

Dad and I jog together. He still lies down on the kitchen floor when we get home. But he says he has more fun with me along.

I guess we all get a lot of exercise around here. There's still one thing I'm not allowed to do.

Mom still won't let me carry Hercules up to the tree-house.
