Our coach does something similar, but he doesn't have them 'fly' over the vault. This is with the 4s getting ready to go 5, and some of the 5's and to get them to punch correctly. He stands in front of the vault, between the springboard and vault. Mind you he is short, maybe 5'2 and built like a truck. Anyway, the girls run full force, punch, he catches them until they are punching up and with enough force to go over how they should for the 5's and safely for the 4's. The higher level girls do a drill where they punch to a handstand on the vault and step down on the vaulting table. For the person who was talking about how the girls might not feel comfortable going full force at their coach I don't have a problem with it for a few reasons. First, during the summer he will walk in front of the vault, bars, etc. right before they get to the vault, bars whatever; using it as a distraction to teach them in a safe way that no matter what the distraction, stay focused on what you are doing. Second, the girls could easily make it over him as he is not much taller than the vaulting table. I should note that he is not the first person I have seen do this. I am wondering if the term 'toss over his head' is what is throwing off some of the responses.
