This exercise is definitely great to help building your lats, chest, your ribcage, seratus, stabilization muscles, and it also helps with your vacuum pose.
This is simply one of the best shoulder exercises. The reason why is because it puts stress on all of your three heads, and it definitely can help you with your shoulder stability cause you twist the dumbell performing it.
Pinch Grip/Steve Revees Deadlift
This was named after Steve because he was the one that introduced this exercise. As a deadlift it helps you with your lowerback development, wider back and your definitely working on your grip while performing this. It’s also good for someone who has lower back pain since this is a more friendly version of a deadlift. Atleast in my opinion.
Vince Gironda put his money on this if we can say so. This exercise is almost not an exercise though its very benefical to those seeking for ab strenght and trimming your waist. You can read more about it at (http://www.bodybuilding.com/fun/ms-fit5.htm)
Wait a second this isn’t forgotten. Well if you’re in a weightlifting or a powerlifting gym it maybe isn’t but in most gyms you never see someone performing it. This exercise hits your quads but besides that it’s also easier on your lower back, its a more natural movement, and you’ll improve your overhead power since this is a similair exercises, and ofcourse it also strenghtens your core.
