Male students' height 1.7 and weight 120. This figure should be ok. Maybe a little thinner or a little fatter. Being too fat or too thin is not good for both men and women. First of all, the face value is very different. As long as you exercise more, control your diet and don't overeat, it won't be too heavy. Whether men and women are too thin or too fat, it is cool for boys to be neither fat nor thin.
