I agree with most of the posts, I'm no expert but my delts were my most stuborn muscle group and yes they are the foundation for that Y taper look. With big delts you can hide a thick waist. If you want cannon balls for delts start with heavy presses front and back on a smith machine then single side laterals as a super set, I also recomend a heavy bag for punching power. Once you begin to feel that projection from your shoulder to the connection with the bag you will see noticable results. You have to see results to feel good about the workout, especially when others see it. Just remember "form follows function". If you get serious about your shoulders they will get serious with you. You wanna draw attention, nothing like cannon balls to turn heads. A great set of delts is like having a second set of tits. LOL
