GTA 6 Character Customization: Body, Weight and Muscle Explained
One of the standout details from the August 2026 Extended Look is a system fans have wanted back since San Andreas: dynamic body change. Rockstar confirmed that GTA 6's protagonists' bodies actually shift over time — here is everything we know about character customization in GTA 6.
Bodies that change
Rockstar confirmed Jason and Lucia can gain or lose weight and muscle over the course of the game. Your characters won't look identical from start to finish — how you play shapes how they physically look.
A San Andreas system, modernized
GTA: San Andreas (2004) famously let CJ get fat or ripped through eating and gym time. GTA 6 revives that concept on modern tech, meaning diet, activity and time likely feed into physique — and potentially how each character animates.
Clothing and appearance
Body change joins the broader personalization Rockstar is building — clothing, outfits and appearance all react to your choices. The new screenshots showing Jason and Lucia in fresh outfits underline how central customization is to GTA 6.
What's still unconfirmed
Rockstar hasn't detailed the exact inputs — whether body change is gym-based like San Andreas, food-based, activity-based, or a blend of all three. Nor has it confirmed whether physique affects stamina or combat. We'll update this guide as details drop.
