Hip flexor - Does it really flex your hip?
Naming muscles according to their function should be viewed critically. Assuming that the hip flexor flexes the hip is correct, but it only reflects its role very superficially. Moreover, this insinuation is only one-dimensional. And as we know, all of our muscles function in all three axes of motion. In childhood and adolescence, the iliopsoas has considerable length, or extensor capacity. This characteristic falls victim over the years, to excessive sedentary behavior and a lack of exercise. In competitive sports, this often leads to a one-sided overload. Under these circumstances, this muscle group loses its mobility and functionality in all three movement axes.
