Wobble boards are sooo fun...

[Mister Obvious]

Oh nah, you definitely wouldn't. It is very easy. It's really about the subtle workings of the muscles and tissue connections you never really notice in everyday movement and stuff. It's fascinating actually. You work things that you never knew were there, but it's gentle, it's not strenuous or anything. They recommend using it barefoot, and I do sometimes because it works different parts... but usually I prefer wearing shoes with it.
