Ganton Gym
The Ganton Gym is a gym in Grand Theft Auto: San Andreas
Description
Located in Ganton, Los Santos, the gym becomes accessible following the mission Drive-Thru. Carl Johnson can learn boxing moves at the gym, as well as use the other facilities to increase or decrease certain statistics, specifically stamina, muscle and fat.
Glitch
One common use for the gym is the hole in the roof which allows access to Blue Hell, which requires the player kill everyone inside, using the jetpack cheat code to acquire a jetpack, and walking towards the door with the jetpack, lifting the player off into Blue Hell. Using this the player can enter several non-used interiors, you can even enter Liberty City, which is a left over object from the mission Saint Mark's Bistro.
