How do I increase a player’s fitness?

If your players are struggling for fitness, then you can visit your club’s Facilities and unlock the Physical abilities within Training to increase Stamina. You should also make sure that you are not overplaying individual players. It is wise to rotate your squad from time to time. If you have a big game coming up and you want your star player to be in peak condition, then you have the option of using ‘Boost Condition’.
