Please tell me, would you say posting is more of a front to back movement rather than up and down? Would you say it is move of a front pubic bone movement rather than less butt movement? (leading with your belly button rather than pushing up with your butt) Also, how do you keep your leg so still? Mine seems to do this "kick out" thing. I think again, a by-product of the up and down.
Any advice on correct and fluid posting would be helpful. I've watched many videos trying to envision the mechanics of how it all should be working. Thanks.
