The push-up is in almost every upper-body workout for women I've seen, yet most women (including myself, up until recently) can't do one. In fact, some data suggests that seven in 10 women would struggle to do the exercise without some training.
That's not on us. Women typically have less upper-body muscle mass than men. Our centre of mass is also towards our lower body and hips. But it is easy to start strength training and to build upper-body strength by working the arms, chest, back, and shoulders.
