im pretty sure this is the 8th time she's mentioned how the weight lifting has paid off. Maybe i'm being deliberately petty or whatever, but i think using a pen only involves the extrinsic flexor muscles of the hand, and as such, weight lifting wouldn't make a difference. So she's either gripping a pen so hard she's using her biceps, or the pen weighs 75 lbs because it's filled with the souls of forgotten characters.
