Fitness is back as a real gameplay system in Grand Theft Auto VI. Working out physically reshapes Jason Duval and Lucia Caminos, changing how they look, how hard they hit, how long they can sprint, and how much punishment they can take. The system revives the body mechanics last seen in 2004’s Grand Theft Auto: San Andreas, rebuilt with far more depth.
Quick answer: Train with weights to raise strength, melee damage, and your health bar; use cardio machines and calisthenics to expand stamina. Eating badly and skipping sleep visibly worsens both characters’ appearance and movement. The entire system is optional and never blocks story progress.
What working out changes for Jason and Lucia
Rockstar has confirmed that food affects Jason and Lucia’s weight, while exercise visibly builds and tones their muscle. Behavior outside the gym matters too. Spending a long time away from a bed, running from police for days, or going on a multi-day bender shows up on their faces and posture.
The effects apply to each protagonist independently. Because you switch between the two, you can end up with one character in peak shape and the other worn down, depending on how you have played each of them.
| Activity | Effect |
|---|---|
| Weightlifting (barbells, dumbbells, resistance machines) | Increases muscle mass, melee strike power, grappling leverage, and overall health |
| Cardio (treadmill, stationary bike, calisthenics) | Expands stamina for longer sprinting, swimming, and climbing |
| Fast food and low activity | Visible weight gain and slower, more sluggish movement |
| Skipped sleep, long police chases, benders | Facial fatigue and changed posture |
Where to train in Vice City
Fitness facilities are spread across Vice City. You can use traditional indoor gyms, boxing clubs, and open-air workout parks scattered through the map. Trailer footage shows Jason working out at an outdoor gym, with his physique visibly varying between shots.
Access is not fully automatic. Before you can start using the machines, you first grab a membership from the front desk. Each location leans toward a specific type of training, so where you go determines whether you are building strength or stamina.
- Indoor gyms for weightlifting and resistance work
- Boxing clubs for combat-focused training
- Outdoor workout parks for calisthenics and cardio
Consumables that boost stats
Beyond the machines themselves, you can drink protein shakes and grab other consumables from vending machines to boost stats. These help you push through more repetitions in each exercise, which speeds up how quickly Jason and Lucia build their conditioning.
The overall design closely mirrors how real fitness works. Consistent effort pays off with better numbers, while neglect causes those gains to slide back.
Is the gym system required to finish the game?
No. Training is completely optional and never restricts progression. You can ignore the weights entirely and still complete the story without hitting any roadblocks. Maintaining peak conditioning delivers clear advantages in fights and chases, but it is a benefit rather than a requirement.
Jason and Lucia can also hit the gym together, so the fitness system fits into the game’s cooperative, dual-protagonist structure if you want to engage with it.
How the fitness system evolves San Andreas
San Andreas was the only mainline Grand Theft Auto where body type was a system you managed. CJ’s weight and muscle shifted based on diet and time at the gym, using timing-based rep mini-games on the machines. Those mechanics were dropped for GTA 4 and GTA 5, though a version of the idea carried into Red Dead Redemption 2.
GTA VI rebuilds and expands that foundation. Rockstar describes the world as more grounded and reactive, where actions carry consequences. The head of development at Rockstar North has said the team revisits older games critically to improve areas they could not fully realize before due to time, resources, or technology.
You can see early hints of this body variation in the first official trailer.
Grand Theft Auto VI launches on November 19, 2026 for PlayStation 5 and Xbox Series S/X.
