Kurt Busch's pit crew performs these drills on Tuesday, Wednesday and Thursday during the season
* THE LADDER DRILL
For 10 minutes all seven crew members run back and forth in a tight line, stepping carefully between the 15-foot-long ladder's sections. "This is for footwork and agility," says Johnson. "We need our guys to move in concert when they jump over the wall, and this helps them realize how the other guys move. It also helps build teamwork."
* LUG NUT DRILL
To build strength in the forearms, a crew member attaches a power-wrench gun to an elastic band, then hooks the band to a belt strapped around his waist. Working against the resistance of the band, tire changers, who also must take off and put on the lug nuts during a pit stop, replicate their usual movements, lifting the gun, hitting all six lug nut marks, then putting the gun down. They do two sets of 10.
* TIRE CHANGER DRILL
This exercise simulates how changers remove the tire during a pit stop--with added resistance. Johnson uses a pulley system to connect the 70-pound wheel to a weight machine, then has his tire changers do two sets of 10 repetitions of pulling the tire out before setting it down on the ground.
