Well exercises are the same and there is no difference in them, a squat is squat be it for a guy or a girl. Squat is going to hit and build the quad muscle irrespective of who is doing it same goes for barbell curls or any other exercise. But the way women respond to exercise does differ when compared to a man. It’s because of the hormonal differences and lack of same levels of testosterone compared to man. That’s one of the main reasons why women will not build muscle to the same degree as that of a man.
It’s better for women to train on high volume rather than lifting heavy weights which can be strenuous and cause injury. They should focus more on toning their muscle and overall health rather than taking their bodies to low levels body fat which is unhealthy and dangerous.
