source for statistics:
1. on weight of man and women i googled to find average male and female weight in the US and i also did find a crossfit link which had the avg male and female crossfit bodyweight. they both end up around 75%
2. on the body strength. i searched records for powerlifting and weightlifting rankings of men and women of the same weight classes. men would get 2x the bench press of women at same weight and squats 1.5x more. thats the average of many different records. The crossfit data i mentioned for weight also had squat and upper body lifts for men and women and when you controlled for weight difference it also averaged at the same as the other strenght competitions for upper and lower body.
Anyone wanting to disprove me just find and post:
1. avg weights of men and women of different nations
2. strength competition lift record (after all we do like LIFT and carry) if preferable of the same weight category for both genders. happy hunting
