How about a Pathfinder Feat?
Constant Training
You are a living weapon, but like any weapon, you must be honed to an edge.
Prerequisite: Monk
Bonus: If you spend 15 minutes a day practicing forms or other martial arts, for the first round you attack in each combat that day, you gain a +1 bonus to all attack rolls for that round.
Thoughts?

I use something like this for monks in my campaign, if they don’t train their katas and forms like a cleric prays for spells they lose some of the bonuses I give the class.
I’m using this for my game now.
