Well - isn't school supposed to be preparing you for the adult world?
Which is where, when women do "physical activity" it very much tends to be yoga, or step class, or legs-bums-and-tums, or pilates, or distance running/ jogging, or dance, or cycling, or tennis, or "going to the gym", or hiking, with a minor helping of martial arts, table tennis, synchronized swimming, mountain clumbing, and soccer.
I really do not see what the big deal is about teams and competition. For heaven's sake I used to play in a works 5-a-side game (where I was the only woman but not noticably the worst player) and the goals were never counted and who was in what team changed from week to week. And most male runners, like female, are mainly trying to improve their own fitness, so how, really, is that all that different from going to yoga or zumba and learning how the hell not to fall over or collapse red-faced in the middle of the session?
