How do you train players???

hi this might sound a stupid question but im reasonably new to fm and i was wondering when you put a player on a individual training scheme wheather or not they will actully get better at what you put them on (e.g. free kicks)

As long as you have very good coaches they should improve, although if their adaptability is low then probably not, with regards to coaches, employ as many as you can and only give them one discipline to train the players in.

I simply let my Assistant arrange all these nasty things...
I couldnt understand the training schedule things since I start playing in the CM era...
