Women Inconsistent Excel Gold Vault

[Taylor Maltby]

So I am an Excel Gold gymnast and for some reason or not I have an inconsistent vault. We do front handsprings or a half on. My half on is actually pretty good and I am not worried about that, its just that my front handspring is not the best. I am just not understanding the concept of it I guess. Some practices its really good and others its terrible. Does any one have any advice? I really want to do well at competition which is coming up in a little more then a month. If you have any drills that I could do at home, or any advice I would so appreciate it!
Thanks!
