I was a gymnast and later coached my son in pole vault. We had a horizontal bar in our back yard from the time my son was 8 years old until college. My son was gifted on the Hbar and could do giant swings as a child. When he was16 we started to use the Hbar for training. Within a few weeks he could hang under the bar and do the maneuver shown where they fronted the bar and went all the way around, only he did it to a full handstand on the top of the bar, from a slight swinging hang. That one maneuver added well over a foot to his PV height, in less than a month. By the tim he started his senior year he could vault 15’ with a 11.5” pole with 6 steps. The HBar is probably the best single apparatus you can use for PV. I will say, I loved the pole with the rope for training also.
What weight/length of pole are they using at 3:00 min into the video? I've been racking my brains how to get this type of setup for my vaulters, but never quite imagined such a simple setup. of course I want it to be safe.... any tips there?
