Log rolling is an activity introduced in The Sims 2: Bon Voyage. Sims can do it for fun or challenge other Sims to log roll. Sims will roll and rock the log until they or their opponent falls off the log; Sims with a low body skill are more likely to fall off. The log rolling activity object, by default, only appears in Three Lakes vacation lots, although it can be purchased for residential and community lots outside vacation neighborhoods. Log rolling builds the body skill, although it does not build fitness.
