My New Work-out Program

I recently changed my workout program. It used to be as follows: Day 1 - Chest and Biceps Day 2 - Back and Triceps Day 3 - Legs, Shoulders and Abs Now, I integrated the 5x5 program whole body workout which also has a 3-day cycle. It is called 5x5 because you only do 5 reps for 5 sets, although the weight that you'd use is 5RM (the heaviest weight that you lift for 5 reps). Day 1 - Bench Press, Squats and Rows Day 2 - Military Press, Deadlifts, Squats, Pull-ups Day 3 - Bench Press, Squats and Rows Since I integrated it, I supplemented the 5x5 program with my previous program. So if I'm doing day 1 of the 5x5, I will add some chest and biceps workout and so on. I'm thinking this is really effective because the muscles always hurt after workout.
