This mount incorporates what I know to be a hip hop transition (or hip hop climb on vertical apparatus), which is why I call it a hip hop mount!
Prerequisites:
It's helpful to have a pullover in your toolbox when approaching this one but you can tag the foot on the bar and learn the pathway even if your pullover is a work in progress. There are other ways to arrive in position for the hip hop transition. You can play around with setting it up from inside the hoop to avoid that straight arm pullover and then you’ve got a transition without the mount. Experiment at will, you have choices.
