The legs don’t surprise me. I’ve worked in a gym and have seen some chicks push some weight. I almost never see a chick do a single pull up though.
Wow! You gotta get out more. Female athletes (gymnasts, pole vaulters) do pull-ups all the time.
Pound for pound, female gymnasts are some of the strongest people on the planet.
You haven't heard about Crossfit women, haven't you. Crossfit women can do pullups, handstand pushups, bench press, and other upper body exercises, putting many, if not most, men to shame.
At the “Y” gym this year I watched in utter awe as an attractive young lady went over to the pull-up bar and proceeded to do a dozen quick pull-ups.
Stood there with my jaw open for some time....found another guy and said, “DID YOU SEE THAT!?!? I’VE NEVER SEEN A FEMALE DO PULL-UPS IN MY LIFE - AND SHE DID A DOZEN!”
