Top arm bending when I jump

[KentVango]

I am running into a problem when I jump and I am having a hard time correcting it. When I jump My top arm is bending and I can't seem to keep it straight when I jump.....Does anyone have any suggestions to correct this?

Suggestion, yes. Remedy? Who knows.
There is a posting in the General Section about Closed Grip Vaulting, and on there VaultFan posted a great link to a discussion of the closed grip drill by a guy at Mt.Sac. You might want to check it out. By doing a closed grip drill you have no choice but to have a tall, strait arm plant. Enough drills like this might translate over to a full vault, it has for me.
Notice that the article states a PROGRESSION from very easy two step drills to longer more advanced methods. Make sure that you follow the PROGRESSION as it is listed, and run it past your coach first, make sure they understand what it is and why you are doing it.
Emphasis in this drill is on a tall plant and a good drive knee/jump off the ground.
Good luck,
