Girrrl, I could barely do a walkover on the beam, let alone any of those jumps. That's not to say I lacked balance...The jumps that are done on the balance beam can have all sorts of deductions that if you weren't taught how to do the jumps you may not see or recognize. Now some of those jumps I've never been able to do, but know what they are supposed to look like so can tell when there are likely to be small deductions.
Did you know some of the women pole vaulters are former gymnasts? At some point their coaches had just said you are getting too tall, let's see what else we can do with your pliable, but too tall, body. (Wish I had had that choice back then, the pole vault looks kinda fun.)
