It's not really a "power" thing. If you want to break their posture there are dozens of ways to do it: shoulder bumps, knee bumps, whizzer snaps, underhook snaps, "shot put" on the underhook side, and just simple footwork all come to mind.
Why are you trying to "break their posture"? What's your end goal? And just so we're on the same page, what do you mean by "breaking their posture"? Getting them to bend forwards? Backwards?
Ater you hug them you should kiss them, but no tongue until the second date
