But you've just done a big twist in the air? For me, momentum, and other good stuff you've mentioned, comes the from back foot landing in a strong and stable position from where it can push-off most effectively towards the target.
When your back foot pushes off towards the target what happens? Your body mass and momentum travels down the pitch towards the target. However you achieve that is irrelevant. Run in spinning if you want to, but at the time of delivery you have to be going towards your target.
But again, dancers aren’t pushing anything towards a target.
You’ve just reaffirmed my point and the point that the level 2 is trying to install, the more of you thy goes towards the target, the better. Yes some kids might want to run in from mid off because they want to be Ryan sidebottom, but generally a straighter run up makes it easier to plant your back foot and get your momentum towards the target.
You’re taking issue with the sentiment of run in straight, when it’s actually trying to achieve the same end goal that you have just admitted is important.
