Regarding exercise, I'll stick with my 50 pressups, 100 situps, 100 squats, 50 pressups, I think it does the job.
Music, any decent music can help intelligence, I recommend underoath personally. Prayer routines, I don't like that idea, if I ahd some fixed routine for prayer it would make it a chore rather than something to do every time I remmember to and as often as possible.
