Practice: Vaulting but not doing the rock back part

[bushy_12]

What is the best and safest way to do those drills where you plant and take off but you do not rock back. You are in a standing position through the while vault. I want to do this to practice keeping my bottom arm from collapsing at take off.

Thanks

Using a soft pole from a short approach.

And continuously try to raise your grip while still staying behind the pole into the pit...
