Deltoid specifics is devoted to helping you learn which exercises target which part of the deltoids. It is about training the deltoids, especially when they need to be brought up to proportion to other parts of the delts/body.
Machine presses, because you can lower the weight farther with machines than with barbells or dumbbells, thereby stretching the front deltoids to the maximum and getting a longer range of motion. Do not lock out on top in any press movement.
Use dumbbells whenever possible to better stress the deltoid heads.
Arnold Presses - Arnold's favorite delt exercise especially when combined with Running The Rack or the Stripping Method
Front Dumbbell Raises for maximum front deltoid and pectoral separation
Front Barbell Presses
Incline Barbell and Dumbbell Presses
Incline Dumbbell Flys
Dumbbell Laterals, beginning with the dumbbells held beside the thighs instead of in front while standing straight or sitting on a bench with your back straight
Cable Laterals, raising your arm from the side of the body, not across the front
Do super-strict Laterals (not letting the weight rise about your head, to ensure that the delts do the work instead of the trapezius).
Do burns after your Lateral Raises (taking very heavy dumbbells and holding them out with totally straight arms about 10 inches from your thighs for as long as possible, but at least 30 seconds).
Use the Priority Principle, beginning your deltoid training with rear delt movements.
Add extra rear delt sets: Bent-Over Laterals, Bent-Over Cable Laterals, Bent-Over Barbell Rows, Seated Cable Rear Laterals, Incline Bench Lateral Raises (facedown), or Lying Side Laterals - try 10 sets for each arm done continuously without stopping.
Take extra care to work the rear delts with the strictest technique possible, since any cheating will allow other muscle groups to do too much of the work.
In all Rear Laterals, twist the wrist as if pouring water from a pitcher in order to increase rear delt development.
