My weight is my mass multiplied with gravity. So is everybody else's, using appropriate pronouns. Don't see why such an universal property of physical bodies would matter in this matter.

OTOH, I wouldn't come close to any sports with connections to, or shaped as, showbiz. If they have a stadium, require special equipment, have their own branch of medicine, may be used as an excuse to pass a mediocre into academia, or make money doing it (any two of the listed is enough) - I'm neither watching nor participating.
