Currently I am doing WWB1, so I'm doing 1 muscle group a week. After reading Lyle McDonald's article

I want to try doing a muscle group 2x a week. So how would I break WWB into a 2 day workout plan Monday, Tuesday, then again Thursday, Friday, from its current Monday, Wednesday, Friday plan?

Chest, Back, and Leg Monday then Shoulders and Arms Tuesday?
Chest, Back Monday then Legs, Shoulders and Arms Tuesday?
or something else?
