GTA 6 will track much more than Jason and Lucia’s weight and physical appearance, with Rockstar confirming that sleep, exercise and fitness can directly affect the characters’ attributes.

New details from GTA 6 preview sessions continue to reveal just how deeply Rockstar is expanding its character systems. Players won’t simply visit gyms for cosmetic changes — taking care of Jason and Lucia can influence their health, stamina and recovery.

GTA 6 Will Track How Well Jason and Lucia Sleep

During a preview playthrough, Rockstar North co-studio head Rob Nelson explained that GTA 6 tracks whether its protagonists are properly rested.

The information can be viewed through a fitness app on the in-game phone, with insufficient sleep potentially affecting the regeneration of certain attributes.

Nelson summed up the level of simulation simply:

“We track lots of things, all this good stuff.”

Working Out Improves Your Character

Gyms will also play a significant role. Players can purchase memberships and complete workouts to improve Jason and Lucia’s physical condition.

A workout session requires three exercises, while different activities can improve specific attributes. Cardio can increase stamina, for example, while exercising more generally can improve health.

Jason and Lucia can even work out together as a date, combining the fitness system with GTA 6’s relationship mechanics. During the demonstrated session, Lucia was also able to purchase a protein shake at the gym.

Combined with previously revealed systems involving food, weight and muscle growth, GTA 6 is taking character management considerably further than GTA 5.

GTA 6 launches November 19, 2026, for PS5 and Xbox Series X|S.
