There is no item literally called "Training Dummy" in base-game The Sims titles. Instead, use these combat-training objects:
| Game | Object Name | Pack Required | Location in Build/Buy |
|---|---|---|---|
| The Sims 4 | Punching Bag | Base Game | Activities & Skills → Fitness |
| The Sims 4 | Martial Arts Dummy | Get Famous | Activities & Skills → Fitness |
| The Sims 3 | Punching Bag | Base Game | Entertainment → Hobbies |
| The Sims 2 | Punching Bag | Base Game | Entertainment → Miscellaneous |
| The Sims 1 | Not available | — | — |
Tip: In The Sims 4, pair a Punching Bag with the "Energized" moodlet (cold shower, protein shake) for faster skill gains.
