Of course there's the Pre-Exhause sysyem, which seems to work very well on the delts. It can be applied to other muscle groups also.
When doing a compound exercise like presses behind the neck, a lighter set of a extension (extending away from the body) movement (lateral raises for example) are done right before. Point being to work the lateral head strongly first and than with the aid of the pressing muscles (mainly the triceps) work the lateral head even more. There is no rest between these two exercises.
Can also apply this type Pre-Exhause movement with lateral raises followed by upright rows or even hi-pulls. With hi-pulls, and a wider hand spacing ,the bar will only rise to the lower pec's, but that all one would need. The hi-pull is one of the better delt exercise around.
With front overhead presses, using the Pre-Exhause system can work well. Some will use front BB/DB raises rather that lateral raises. Some have tri setted this while doing front raises, lateral raises and finally front overhead presses. Your choice to which works best for you. And again, no rest between exercises. 3X8-10 usually, with this protocol being the only direct delt work done in a training session
There is also the Running The Rack system, for some very advanced and painful delt punishment. Either start at the lower end of the DB rack, or at the top weight (for you) db's. . Most guy's start at the higher weighted DB and work their way down until a 10lb db feels like a hundred pounds.. Can either do lateral raises or DB overhead presses....your choice.
