How about bringing back the Viking raiding party? If you have school-age kids, you can also act out the historical component for possible extra credit (buy some horned helmets and shields).

Raid your neighbor’s houses for food and booze, thus burning off some calories whilst you pillage and plunder. Your kids get the benefit of a historical re-enactment, you not only take off some unwanted pounds, but get free booze and food as well.

If you’re not keen on Vikings, you can do a Pancho Villa motif or whatever strikes your fancy.
