The part where Cynthia Rothrock does a back flip "with a broken arm" is particularly funny.
It'd probably hurt with the motion she did, but it does look like she only fully contacted the ground with her good arm. So I'll give it a little credit.

Some more Cynthia action...
Yeah, she's a great fighter when she has great choreography and partners. Richard Norton and her were apparently buddies, and they partner well together in those scenes which is why he shows up multiple times. Norton could keep up with Jackie Chan himself in fight and stunt scenes, so you know he's got skills.
Fun fact, the white guy she's fighting at 5:50 is Jeff Falcon, probably best known to people here as Buddy in Six-String Samurai. I wish he'd gotten more lead roles. He's a great kung fu performer and had real screen presence. Shame he didn't get more chances.
I like her fight with Sammo Hung:
