It is simple to look at a person's training signs, that is, to ignore those born, such as naturally upturned hips. Without good training, there will be no obvious boundary between the back of thigh and buttocks. The training marks here are reflected in the clear dividing line between the back of the thigh and the buttocks, which is what we call the hip line.
The quadriceps femoris will be tight and slender, and even if there is no fat loss, the legs will not have an independent sense of lines like untrained women.

It is latissimus dorsi. If you don't practice in this place, you won't have it. Women are born weaker than men's upper limbs, so it is very important to judge the traces of female training according to the muscle mass of upper limbs.
