Gym
Gyms are facilities in GTA San Andreas where the player can train to improve his/her physical stats. Indoor gymnasiums are unlocked after receiving a phone call from Sweet after the mission Drive-Thru, introducing the player to gymnasiums. All Gyms are open all day, every day. If, in a single day, the player loses 40% fat or gain 20% Stamina or Muscle, the player will have to wait 12 hours before being allowed to workout again.
To find a gym, view the map in the main menu and select the gyms icon in the legend (a dumbbell).
Fighting
Each gym has a trainer with a different fighting style. At each, walk into the marker and reply positively when the trainer asks if you want to learn some new moves. The training takes a tutorial-type approach, with tips on-screen to tell you how to execute the moves and when. You must defeat the trainer to learn the new moves. Each teaches you a new Running Attack, Ground Attack, and Combo Attack.

Equipment
Each gym is equipped with four pieces of exercise equipment:
Treadmill
This exercise increases Stamina and sheds Fat. The treadmill offers 10 speed levels (the higher the level, the faster your stats will change). Higher levels are easier with greater stamina. When CJ begins running, power and distance gauges, as well as a level indicator, appear on-screen. You must keep pace with the treadmill to keep the power gauge full - if it empties, you fall off.
Stationary Bike
This exercise increases Stamina and sheds Fat. The stationary Bike offers 10 speed levels (the higher the level, the faster your stats will change). Higher levels are easier with greater stamina. When CJ begins running, power and distance gauges, as well as a level indicator, appear on-screen. You must keep cycling to keep the power gauge full - if it empties, you'll have to start over.
Bench Press
This exercise increases Stamina and sheds Fat. The weights range from 40 lbs to 320 lbs. When you begin, a power gauge and a reps indicator appear on-screen. You must get the power gauge to fill to complete one rep.
Dumbbells
This exercise increases Stamina and sheds Fat. The weights range from 20 lbs to 110 lbs. When you begin, a power gauge and a reps indicator appear on-screen. You must get the power gauge to fill to complete one rep.
Glitch
There is a glitch that prevents you from using any equipments and complains that you have trained enough even if you haven't trained in a long time. The glitch is most commonly caused by saving at Madd Dogg's mansion but can be triggered by rare events, too. The main cause is saving the game while equipments are nearby. The best way to avoid this glitch is not to save at that mansion.
Secret
If you have a camera, zoom in on the sides of the dumbbells. You can see the logo of the Cherry Popper ice Cream Company.
