Battle Arenas are places where players battle against enemies using a variety of weapons. Also, the more times you go into a Battle Arena, the more difficult the fighters get.
Easy Gym[]
In this Battle Arena fights are restricted so no weapons can be used. Instead, only fists are allowed, which pretty much makes these fights Fistfights.
Gangster HQ[]
This Battle Arena is harder than the Easy Gym and the opponents are the Westside Gangsters. Upon completing this Battle Arena for the first time, the player receives the Double Barrel Shotgun, on top of increased Strength, Charm and some money. Subsequent completions will only yield the increased stats and cash.
The Lab[]
The opponents in this Battle Arena are Professor Ansel's minions, Assistant Greg and Professor Ansel himself. Completing this Battle Arena means you've won the game.
Mobster Tower[]
This Battle Arena is in an apartment, and the opponents are the Eastside Mobsters. The layout of the map makes this Battle Arena easier to win; you can clear out the Mobsters room by room before taking out the Mobster with the biggest gun at the end of the corridor. Upon completing this Battle Arena for the first time, the player receives the AK-47, on top of increased Strength, Charm and some money. Subsequent completions will only yield the increased stats and the money.

The opponents in this Battle Arena include Westside Gangsters, Eastside Mobsters, Crazed Sewer People and other NPCs that can be fought. Fighting in this particular Battle Arena has a chance of being sent to jail.
The Old Abandoned Warehouse []

Upon completing this Battle Arena for the first time, the player receives the Hyper Drive , on top of increased Strength. Subsequent completions only yield increased Strength.
Sewer[]
In this Battle Arena the opponents are the Crazed Sewer People, who have significantly higher health than any other type of opponent.

Jim's Gym[]
In this Battle Arena, there are two types of fights that can happen: Fistfights (during the day) and Chainsaw fights (only at night). The fights that take place here are restricted as well, similar to the Easy Gym Battle Arena. The only new thing is that for Chainsaw fights you are restricted to fighting only with Chainsaws. No fists. This Battle Arena can only be accessed if you have Director's Cut.
