I apply individual training to "better" players, i.e. first eleven, and some key subs. The remaining players are given "one size fit all" training every morning to boost the bonus to 10%.
Are all players in your squad high quality players and/or very young promising fast trainers?
I've said this elsewhere recently, but I think it's worth saying again here.
If you have a full squad of 25 or even 24 players it is possible to gain the 2% training bonus every day without resorting to watching videos.
The only other thing you'll need are 2 condition gains of 6% each before your next match.
