There are two limitations to training:
- Maximum player abilities: players all have a maximum possible value for each ability. You cannot train them over this value but can still improve their abilities with gear.
- Coach abilities: a coach cannot train a player further than his own abilities.
You should look for a better "Basic" trainer to start with.
Indeed, there are several types of coaches and each type has his own set of exercises. Your team's default coach is a "Basic" coach and unlocks an exercise for each ability. The other types of coaches ("Technique", "Physique", etc.) do not improve the default exercises but unlock new ones. See "How to unlock new exercises" for more information.
There are several possible reasons:
- Players are injured: select the "Injured players" tab to view them. You can heal them with crutches and bandages in the gear section.
