Double Bounce Walk

For my next animation I wanted to try a double bonce was.
John K Animation Blog
I was looking at John K's animation blog as I feel he enplanes the double bounce walk cycle very well.

"In a normal walk a character goes up and down once each time he takes a step. Usually when you step, your leg bends DOWN to take the weight then it pushes UP on the way to the next step. There are endless variations of this, but that's the concept.
In a double bounce walk, you go up and down twice in each step.
Not only do you go down as your foot contacts the ground, you go down again in the middle of the step.
WHY??? A double bounce step is musical. It's like a dance. It's fun. It's in lots of 30s cartoons. Porky Pig in Clampet's cartoons always walks double bounce. It shows that he's youthful and full of pep. It also conveys innocence."
