It sounds like you are just not in love with total body workouts.
Perhaps it is time for you to get away from that format and try more intense weight training such as the Gym Styles offer?
Think about exactly why you do not feel motivated by the total body w/o's you already have, and ask yourself what your goals are and what style of training you want to do. If you have never done split workouts (i.e. chest and back one day, shoulders, tris and bis another, legs & glutes another) before, now may be the time to expriment. You never know what you might like until you try it, and you clearly do not like total body w/os!
