Will this rule be considered a suspect, quasi-suspect, or non-suspect classification?

The city of Martinville passes a municipal rule stating that all firefighters must be able to life at least 200 pounds of weight to be eligible to serve as firefighters. Marsha challenges this regulation on the grounds that it discriminates against women, because most women are not able to lift as much weight as men. Will this rule be considered a suspect, quasi-suspect, or non-suspect classification?
