Another UNIque Ab Hack?

I heard recently that unicycling is a tremendous ab workout.

And when I informed my wife of this last night she rolled her eyes 720 degrees.

She knows that I might actually go get one!

But I have to confirm that it's really a killer ab workout first.

I do have a lifetime record of trying out funky new exercises - all the way back to when I was 14 and was the first one in my circles to buy those *platform* Strength Shoes.

BTW they WORK. At 5'10 and with a lily white complexion I could, back in my day, grab the basketball rim with two hands.
