My DD(8) seems to struggle with vault. She is all of 3 1/2 ft and weighs about 36 lbs. She doesn't seem to get much height off the springboard and tells me it doesn't move very much when she jumps on it. I'm not sure if she is not running fast/well enough and her timing is off hitting it, or if it is because she is so light, or a combination of those things. I was thinking of setting up a few privates for her to work on it with her coaches. I was wondering if there is anything else she can do to help her other than that? Jumping/hurdling exercises maybe? Or might this just be a struggle until she maybe sorts out the technique better and gets bigger and gains more muscle (although I don't know when or how much bigger she might get)?
