The beauty of a push / pull workout schedule is that it minimises the overtraining of any particular body part. This can be evident in traditional bodybuilding workouts where you would train chest, shoulders, arms and back all on separate days. When you actually look at the exercise selection, there if often 3 times as much pushing than there is pulling.  Combine this with the common finding of weak and under active rhomboids / mid and lower traps and the prevalence of an upper crossed posture in society, the likelihood of injury is extremely high. Most commonly, shoulder impingement, rotator cuff tenditnopathy, bicep tendinitis and so on.
Personally I use a 3 day weights schedule as I also combine this running, swimming,  cycling and core workouts. If you are less inclined to perform the cardio workouts then you can use the 4 day workout schedule outlined below.
Furthermore, these workouts below donÔÇÖt outline the specific warm ups / corrective exercises or core workouts.
These are the exercises I currently use but they can be changed for similar exercises that fall into the same category. See bottom of page.

** There are many more exercises you can do but this list gives you an idea of the variations you can employ, however to make progress, exercises should not be switched up regularly. You need to track your weights over a 4-6 week period before switching reps schemes / exercise selections. Otherwise youÔÇÖll never see if your progressing. **
