Signed up to walk my first ever in my life 5K at the end of this month and I'm already getting some improvement in my balance with just walking more and faster.

Tell me more about the slackboard... any particular way you play with it? 41 and have lost what very small amount of snowboarding skills I had in my 20s before I was 30. I have looked at them and the balance boards because I know I need to do _something_.
