If some of your players are not fit to their the schedule, so you should arrange the schedule for your players. For example if your striker is more of a flair based player, you might fancy training them on the attacking midfielder regime. Or in reverse an attacking midfielder who is fairly clinical might benefit from striker training. Here, I will tell you about Football Manager 2010 (FM 2010) Best Training Schedule. If you didn't know about the schedule, so all credit for this one must go to the author, Tug. In tug the good thing is that the training schedule has both youth and senior schedule.
First you must download the schedule at Tug's Site. Then you must place the two files into My Documents\Sports Interactive\Football Manager 2010\Schedules (if there is no “schedules” folder you can create it yourselves), When you're on the training screen in game, click on Edit training, go to import, select the Training files and click OK one file at a time.
Hope this post will help you to train your players in FM 2010. Good Luck.
