The reason that gymnasts are so huge, is due to the disgustingly high amounts of time under tension as they execute their holds and movements. If you have the time to train like they do, more power to you. It's not a feasible training schedule for most people however. Incorporating some of those moves into your workout will yield you benefits, let there be no doubt.
That being said, stick to the basic movements, get really good and really strong at them, at that will give you the best results in the long term.
