One of my favorite "every now and then" moves for the shoulders is an overhead press done with a barbell in each hand.
To do this exercise, you need to set the pins in the power rack so that they are just below shoulder level. Place (2) olympic bars across the pins and then get between them so that you are facing the side of the power rack, rather than the front.
You will have to experiment with your grip to find just the right spot to have the barbells level-this is very important. Use one hand at a time to test which spot works best. Grip the bars so that they are resting on your shoulders parallel to one another. In the starting position, the bars are resting on the pins and your legs are slightly bent. Stand up with the bars across the shoulders and give the bars a chance to level off.
Press the bars overhead to a locked out position-The reason this is an effective movement is that you must do it slowly and with a great deal of control. If you try to "power" the weight up, you will quickly find the bars whipping up and down and out of control. This will force you to do the press slowly, which is perfect for deltoid and upper back stimulation.
The length of the bars and the nature of this exercise will also have a positive effect on the stablizers of your torso.
Start with the bar-believe me a 45lb bar will feel a lot heavier than a 45lb dumbell. Work on slowly adding reps in a smooth, "near perfect" fashion. The legendary Tommy Kono (and if you dont know who Mr. Kono is, you should) was able to press 135lbs for one rep in each hand at a bodyweight of 175lbs. I was able to duplicate Mr. Kono's feat last summer, but then I found he that he did it without any ANY COLLARS---back to the drawing board. This is an excellent adjunct move to any pressing program or it can be used for a couple of weeks to give your shoulder joints a break from heavy presses. In addition,
it will draw the confused stares of your fellow gym members, which makes it a perfect exercise to perform.
