One usually straddles something (what you all are talking about are wide-stance push-ups). I think these are the type of push-ups that are also in High Step Circuit: you put your feet on the high step (set at about 8"), do a push-up, then remain in push-up position and straddle the step (one foot down on each side), perform a push-up, then put both feet back on the step, and so on.
