What codes reward in Gym Star Simulator
Codes mainly provide consumables and boosts that speed up training and competition performance. These include protein bars for temporary strength boosts, energy drinks that reduce stamina costs, and essential oils that increase competition rewards. Spins are especially valuable because they grant random bonuses without waiting for cooldowns.
