It's a mod, mod, mod, mod, world!

[Tom Rice]

You can personalise almost every element of San Andreas, from CJ's tattoos, to fightnig style and even his physique. There's no fitness formula as yet so, for example, ten beefburgers don't equal, say, a three mile BMX ride (or one mile run) to work the weight off. Your fatness effects the way pedestrians treat yuo, and makes certain missions harder if you're unfit. Honestly, the mind boggles.

-Fatness isn't directly linked to strength.
-CJ's recovery time improves the more you exercise - just like life
-Some vigorous bag work at the gym builds up your stamina and strength
-CJ gets to mod his cars with sexy new bodywork and paint jobs
