I was watching the Nastia cup videos last night and noticed a lot of the girls doing jaegers on bars. It got me thinking. What goes into the decision to train one release over other ones? I have seen clubs and lower ranked college teams where almost all the girls have the same release. Usually a Jaeger. Is this just because it is an easier release? (And I know the term 'easier' is relative - they are all hard) Is there a hierarchy for releases, in terms of how difficult they are to train or is it really more with how the gymnast swings and flies?
