I'll describe the ones I know:
Lie on a bench like you would bench press, while holding one DB with one hand. Extend your arm to full lockout, and use your scapula only to move your arm up and down. Scap pushups are another variation of this exercise. Get in pushup position and only move your scapulae.
A power rack with pins is needed here. Set the pins so that the bar is at hip level (or however your program says, it may be different). Get under the bar with either a front or back squat stance, depending on programming, and start squatting. More than likely you will be using less weight than a regular squat.
Grab DBs and hold them like you're about to do some upright rows. Begin by performing an upright row until you get to your nipple line. Then, externally rotate your shoulders until you get into a shoulder press position, and press the weight overhead. Reverse movement for eccentric portion
Similiar to the cuban press, but a little more explosive. Sit down with DBs hanging to your sides. Then, use your traps to power up the DBs while also externally rotating the shoulders. Unlike the cuban press where the DBs stay close to your body, the clean motion creates a big arc (think Oly lifting). End in the "bottom overhead press position".
I won't get into specifics with the squats because I don't change my stance all that much and aren't familiar with the theory behind all the variations. I guess my stance is more power squat-ish, with a stance a little bit farther than shoulder width, with the bar resting on shelf between my middle traps and rear shoulders. This stance seems to work my legs evenly (quad/ham/glute) so I have no complaints.
