Gym

The city gym is the main paid training spot for sports, looks, and fighting — separate from the prison gym while you are jailed.

What you can do

• Workout / lift weights — Costs money each session; skill challenge reps. Success trains sports, raises looks, and spends energy through the activity. Available here or at the prison gym if you are inside.
• Boxing match — Entry fee plus a timing mini-game (stop the marker in the green zone). Win: cash, fighting and sports, morale, and wins count toward knockout-style achievements. Lose: big health and morale loss. Boxing gloves make the timing window a bit wider.

When to visit

Prioritize when you are building fighting for crime, patrol fights, or brawls, or looks for careers and romance. Skip if you are broke — losing a boxing match hurts.

Strategy

Wear boxing gloves before matches; the extra window combines with your fighting and sports levels for easier timing.
