You want flexion in the ankles and knees.
Is this hitting stance better suited to females than males? That's the part I found most interesting from SBF - ''Stay tall is a problem for most females.'' I don't have an opinion on that, just hadn't thought of it. A hitting coach has told my DD not to bend over, but he was referring to bending during the weight shift forward/stride, not the stance. Just made me curious.
