Shoulder training

My weight training program for shoulders are as follows:

* Standing overhead barbell press - 5 sets 8 reps. Do set to failure, rest 15 seconds. Do again til failure.
* Upright row - same as above.

* Dumbbell side raise - same as above.

* Dumbbell front raise - 5 sets 8 reps(forced reps)

* Barbell shrugs - 5 sets 10 reps. Do set to failure, rest 15 seconds. Do again til failure.

* Dumbbell shrugs - same as above.

I do a little cardio twice a week. Today I used the treadmill for 20 minutes. It's scientifically proven that cardio after weight training is more effective that doing cardio before weight training.
