Weight machine

Weight Machines are objects in The Sims, The Sims 2 and The Sims 3 used to improve a Sim's body or athletic skill.

"Exerto" Benchpress Exercise Machine
The "Exerto" Benchpress Exercise Machine is the default exercise machine for The Sims. It may be the product that launched the Exerto brand of exercise machines and bodybuilding equipment.

The Machine Workout Bench
Superstar added a high-priced "prestige" exercise machine called The Machine Workout Bench. It raises a room's Room score, but is no better at building the Body skill.

The Sims 2
The Exerto 5000 Multipress Exercise Machine is the default weight machine for The Sims 2. University added the Exerto Butterfly Exercise Machine, Exerto Free Press Exercise Machine, and Exerto Leg Extension Exercise Machine, which are basic, single-function machines that cost §900 instead of §1400, and have a Fun rating of 1 instead of 3.

Sims can use these machines until they become fatigued. On community lots, uncontrolled Sims almost always ignore weight machines. An uncontrolled Sim on a community lot may use a weight machine if all treadmills in the room are being used, but this is uncommon.

If Seasons is installed, Sims' temperature will not change when using exercise machines, as it does when using the treadmill and exercise bike. Sims will also gain Fitness hobby enthusiasm if FreeTime is installed.

If FreeTime is installed, the Exerto 5000 can be tinkered with, but the less expensive weight machines from University cannot.

The Sims 3
Sims can use it until they become fatigued. It increases the Athletic skill, specifically the strength (as opposed to cardio) aspect of a Sim's fitness. Sims with high Athletic skill can train other Sims on this object. Weight machines are commonly found in the Gym and Academy lot types, alongside Treadmills (and in the latter case, Board Breakers and Sheng Hai Training Dummies).

Trivia

 * In The Sims 2, playable sims will never autonomously use the exercise machine, even if they have full active points, a red fun bar, and there are no other items for fun on the lot.
