How about you focus on training your WHOLE body like a bodybuilder for five years and then see what your shoulders look like!
Here's the top secret formula:
Small muscle groups: two to three exercises
Large muscle groups: three to four exercises (back might need up to five)
Sets: 2 to four sets
Frequency: once every five to seven days
Use compound, isolation and machine exercises that hit your body for YOUR needs.
Sequence exercises appropriately.
Split the body over four days.
Reps: 8 to 12 most of the time, sometimes 6 to 8.
Lift two or three days on, one day off.
There: I just gave you the top secrets of every alright bodybuilder, from the decent to the elite!
As for nutrition, eat protein and carbs four to six times a day with veggies and a small amount of good fats. Again.. Like every bodybuilder on earth!
Anymore detailed guidance requires you read up and learn from associating with bodybuilders or hiring one to do the brain work for you!
Do this for five years and see what your shoulders and rest of your body looks like. Then you can worry if your delts are not popping enough, not when you're asking questions for results people can't predict!
