Over the last year, I have been dedicated to the gym three days a week. Over that time, I've been concentrating on adding muscle mass. My normal routine is the following (mixed up three exercises per muscle group, two muscle groups a day three times a week):
Shoulders: arnold press, military press, clean and press, shrugs
Back: deadlifts, rows, hyperextensions, reverse fly
Legs: leg press, calf extensions, squat, lunges, forward/reverse leg extentions
Chest: bench press, inclines, declines, flys, cable press
Triceps: skull crushers, various rope pulldown, various dips
Biceps: preacher culls, standing culls (21's), hammer curls, cable curls
What these exercises have done over the last six months is basically double my strength across the board (from 90lb benches to 170, from 300lb leg presses to 600). However, I really want to start concentrating on golf muscles now that the season is starting. I know that shoulder and back exercises should help, but in the above list, what am I missing that will really help my game? Is there anything I should cut back on?
