Serious question - Can you play Wii Fit on your butt?

[NJ5]

First I was sitting like this (except the arms were relaxed atop the knees).

Then I realized it's better to sit like this (again, arms relaxed, no need for stretching).

The first way is fine to play games which only involve sideways interaction (such as football headers and ski slalom), but with the second way you can also play games which involve interaction in all directions (such as Balance Bubble or Table Tilt).
