"DAVIDSON, N.C. ? The laws of physics explain why there aren't any female members of a NASCAR pit crew: The average woman of 5-4 weighs around 130 pounds, and the average racing tire weighs between 55 and 70 pounds. So physics explains a woman of average size would have to lift and move half her weight ? twice ? and bolt two tires in 12 seconds or less to succeed in a NASCAR pit.
Lifting a tire wouldn't be a challenge. One of the standard CrossFit workouts involves flipping a tractor tire. Even the fuel can, which can weigh up to 90 pounds, wouldn't slow down Abbott. Nor would jacking up a car. Easy stuff for her. The hard part would be drilling the bolts on the tires once they're on the wheel. The pros do that six times in 1.3 seconds.
Physics never met CrossFit Gym owner Christmas Abbott."
