My base weightlifting routine was: Chest/Back, Biceps/Triceps, Legs, Shoulders and an extended core. After awhile I would switch to your split and do it that way awhile. For a long time I was doing as many as 8 exercises for each muscle group, three sets each, mostly super sets. I thought that really was overkill, especially since I'm not training to play professionally, so I cut that down to 4 or 5 exercises per muscle group.
Now I mostly do body weight exercises. I can do it pretty much anywhere, so if I travel for work I don't have to miss workouts (though back can still be a challenge). I can also get a really good workout in 30 minutes. I will do each muscle group more often, 3 to 5 times a week, but it is made up of shorter workouts. I still get really good results, and there are so many variations on things to do that it never gets boring.
The creativity available for body weight training is one of its most appealing aspects. I was thinking one day what I could do to work my shoulders, so I went to the wall and got into a handstand against it and started walking lower down close to a flat plank with my feet on the wall, then back up. Just doing that 3 times is a challenge. It really is something where you can make something up on the fly and challenge yourself to do things you never thought you'd be able to do. Even if you are committed to lifting weights, I would strongly suggest trying a body weight routine for a month or so while taking a break from the heavy weights.
