Every year, the gym teacher gives a pull-up test. And every year, Travis Underwood fails. He's sick of it. He's sick of the gym teacher making fun of him. He's sick of watching muscleman Rocco strut around the school. He's sick of being out of shape. So now he's going to get really buff. That's right, Travis is going to start working out. Soon he'll be able to wipe the floor with Rocco. At least he hopes so. But he finds out that there's more to getting in shape than joining a gym. And he realizes (ouch!) that the sign on the gym wall says it all: "No pain; no gain."
