The above, really. I think I would feel quite empowered if I could pull it off so really want to try (with benefit of much-needed strengthening of core and shaping up a bit along the way). But how to get there? Just keep on trying until I eventually can - like I did when I was a child (although it would have never been 10 seconds!) or is there a better way to learn to do this now in mid 40s?
