Workout Routines and Splits - weightlifting and bodybuilding programs

Workout routines are what exercises, how many sets, how many reps etc. that you do for each muscle. For example, 3 sets of the flat bench press, 3 sets on the incline bench press, and 2 sets of flat bench dumbell flyes is an example of one of the many chest weightlifting workout routines. A workout split is a term given to how you split up your workout. What days you do what muscle on. For example, doing biceps back and legs on Monday, and doing triceps shoulders and chest on Thursday is a workout split. Here i will give you some sample workout routines, the routine I use, and tell you how to make your own workout routine.
One rule when making weightlifting workout programs is to make sure to split it so that you aren't overtraining. Doing chest on Monday, then triceps on Tuesday, then shoulders on Wednesday will overtrain your triceps. Why? Because just about every chest and shoulder exercise works the triceps secondary. And almost every back exercise works the biceps secondary. So, you would need to do 1 of 3 things when making your workout routines and splits:
1) Work chest, triceps and shoulders on the same day, and biceps and back on the same day so that its ok if the secondary muscles get worked that day, because your doing them anyway
2) Separate those muscles that work a secondary muscle so that they are far enough apart not to overtrain you. For example, do Chest Monday, triceps on Wednesdays, and shoulders Friday... and biceps Monday with chest, and back Wednesday or Friday.
3) This is personally what I prefer, and do myself. Do chest and triceps Monday, and shoulders Thursday, and back and biceps together on Friday.
