Fitness (attribute)

For the hobby with similar name, see Fitness.

Fitness is the body shape of Sims. Each Sims have different fitness and it depends by how well Sims maintain their own body shape. Generally, Sims can change their fitness by working out or stuffing themselves up. Fitness don't essentially affect anything to Sims other than their attributes and looks, though in The Sims 2: Nightlife, it will affect whether a Sim is attracted to a fit or fat Sims.

The Sims

Sims don't have the actual body shape in The Sims. No matter how much they eat or how long they work out, their body shape stays the same. Sims who are fat or thin cannot change their fitness by any means.^{[confirmation needed]}

The Sims 2

The attribute of fitness is a new feature in The Sims 2. Each Sims have the fitness scale that can be seen in their Simology panel. The scale ranges from Fit, Thin, and Fat. By default, Sims, townies, and NPCs are all thin, and their fitness scale are exactly in the middle. The player however can create either thin or fat Sims from CAS or Body Shop, but not fit.

Sims can build up their fitness by working out, swimming, doing yoga, log rolling, axe throwing, doing Tai Chi, ballet dancing, jogging, or playing sports. Some Bodybuilding activities however don't impact fitness, such as jumping rope and playing on playground. Eating after their hunger need is full will add Sims' fatness and eventually make them fat. Not all hunger-fulfilling activities will add fatness though, such as drinking juice.

Body skill does not impact Sims' fitness. Sims may or may not build Body skill while gaining fitness. For example, Sims can swim or work out in community lots, which will add their fitness but not gain body skill; or that Sims can jump rope to gain body skill, but not fitness. Note that Sims can build fitness in community lots, but their body shape will not change until they go home. Their fitness scale might be full, but they will not become fit while away from home. Sims may not change body shape immediately after reaching the fat or fit scale, but they will eventually after eating, taking bath, or after doing any activities at the end of action queue.

There is no direct impact of fitness for Sims, until Nightlife. Fitness and fatness are one of Sims' selection of turn-ons and turn-off. Therefore, Sims whose turn-on is Fitness will be attracted by fit Sims, or Sims whose turn-off is Fatness will be repulsed by fat Sims.

Sims whose aspiration is Pleasure or Grilled Cheese have the Aspiration Benefit to change the gain of fitness. Pleasure Sims have the Fast Metabolism Lifetime Benefit, which will enable Sims to gain fitness 50% faster, while Grilled Cheese Sims have the Bottomless Stomach Lifetime Benefit, which will enable Sims to lose fatness 50% slower. Having both of these aspirations as primary and secondary aspiration will give the best combination of gaining fitness.

Be aware that even though PlantSims and Servos still can eat, but since their hunger needs are considered full, they will automatically gain fatness. Servo and Bigfoots can become fit or fat, but they don't show any physical differences. Witches have the ability to cast spells to change any Sim's body shape, including ghosts. After reaching level 1 of Magic skill at any alignment, witches can cast Corpus Athleticus to make Sims fit or Corpus Fleshicus to make Sims fat.

Through Cheat

With testingcheatsenabled true, by shift+clicking a Sim, the player can choose to make Sim fit or fat instantly, but not thin.

The Sims 3

Fitness in The Sims 3 has been enhanced from The Sims 2. Sims no longer have fitness scale that displays the accurate Sims' fitness. The only way to tell their fitness is by their physical body shape. Sim's body shape changes gradually through working out or overeating.

With Fast Metabolism Lifetime Reward, Sims gain fitness faster and lose fitness slower, much like the Pleasure and Grilled Cheese Aspiration Benefits combined. With Body Sculptor Lifetime Reward, Sims can choose to instantly make them fitter, thinner, or fatter, though the machine might malfunction.

CAS Sims have the body slider to change their body fitness, and unlike The Sims 2, players can create fit Sims in CAS. In Late Night, a new body slider is added: Muscle Definition. This slider enables to change the muscles of Sims. Muscle definition cannot be gained through working out, and is genetic.^{[confirmation needed]}
