Found an interesting video of a fitness model doing some half-assed one-handed chinups. While they’re not quite one arm chinups (nor are they really complete chinups either), it is impressive to see a woman who can actually come close to the upper body strength of a Lillian Leitzel (who was alleged to be able to perform multiple one arm pullups with both arms).
More about Lillian here – scroll down to her entry in the tables.
BlondeChic has a ways to go yet. So do I.
