It's actually a couple comments from a jujitsu instructor that pushed me towards weightlifting. He really emphasized that provided both parties have a basic level of training, it always takes a disproportionately large amount of skill to make up for a difference in size.
If you think about it, many combat sports have narrower weight classes than strength sports where performance is very directly related to bodyweight.
Now you've go me browsing gymfuckery.
Is it just me or is that a hell of a vertical leap for a woman?
Nevermind, upon further review she appears to be a pretty elite lifter.

This looks like a legit way of teaching proper deadlift technique.
