I have female students who scan the web looking for fun ways to work on their booties and legs. In doing so, they stumble on these videos that are... well... Let's just say that the producers know they're getting a response.
Here are some very fun ways to think about the Sanchin tuck. This borders on erotic dancing to rap, but this young lady is the real deal. Note the combination of flexibility, coordination, and strength. And I have no problem with the cheese, but then that's me. Much of the "wave cheese" by the way is the kind of coordination needed for me to be able to teach someone body-whipping motions in Sanchin.

You got problems with "Uechi Hula"? I don't. The person who came up with that expression by the way (to disparage a well-known Okinawan Uechi master) is totally incapable of any such motion due to ... uh ... excessive fattitude. Eat your heart out, beach!

Here are ways to work on strong legs and booties. Kayla obviously was gifted by Nature. That said, she's got great strength and endurance, and perfect technique. View all the way to the end where she does explosive movements based on an Olympic-style clean.

A shout out to my female students who know how to keep their sensei both informed and entertained.

Don't sit like a pervert and hide this from your wives and girlfriends. For god's sake... pass it along to them. These exercises are much better when viewed in the flesh, and the results speak for themselves.
I do similar work on my own. However, I do it with weights (and fewer reps) and I spare my gym mates any public displays. The booty gyrations however should not be done with weights. Resistance training for those degrees of freedom of motion need to be done a few degrees of freedom at a time to avoid back injury.
