The pressure for female dancers to be slim and feather-light is often at odds with their need to be strong. This contradiction is especially misleading in partnering. "Sometimes, a woman who has more muscle mass may weigh more but is actually easier to lift because she's stronger," says Matt Kent, associate artistic director of Pilobolus. "You don't want to be a sack of sand. Any male Pilobolus dancer can tell you the difference between lifting with a woman who has that kind of strength and one who doesn't."
