The secret is to refine your internal machinations to the point that they are inperceptible from without. It's all about being able to "hug the tree," etc., without visibly doing so.
That way, you can train to your heart's content and none will be the wiser, and, more important, you will not embarrass your children in public.
No, I'm sorry, a dad's solemn duty is to embarass their children whenever possible. Keeps them grounded...
