Exaggerating the size of the skeletal alignment will lead to postural instability.
There will be a considerable number of evident weaknesses.
No posture is impregnable, but an overly-extended framework is liable to promote
tension when put under pressure.
The larger your frame, the less mobile the joints are.
Similarly, a frame that is too small will provide excellent
mobility and the ability to move rapidly, but no skeletal balance or strength.
