…delicious pulled pork shoulder.
I know, it’s not the shoulder you were thinking of, but I’ll get into that in a minute.
I just thought that anyone out there cutting weight may like the image. I don’t know why, but I used to watch a lot of Food Network back when I was cutting weight.
So for anyone out there who’s like me, I hope this brightened your day!
Anyway, on to the point…
Quick Grip Adjustment
I’m going to draw some conclusions based on the research I’m about to present. Please keep in mind that some of my suggestions to follow are not directly based on the research. Rather, I am drawing conclusions based on the data.
The purpose of the study was to measure and assess the impact of hand position on the activity of the posterior deltoid muscle while performing a Reverse Fly exercise on a machine.
A secondary purpose was to measure and assess the effects of the different hand positions on the activity of the middle deltoid and Infraspinatus. The Infraspinatus is one of four muscles of the Rotator Cuff. It is responsible for external rotation.
It has been shown that without optimal performance, specifically downward pull, from the Rotator Cuff muscles, the head of the Humerus is driven into the Acromion process. This causes impingement and subsequent pain and dysfunction within the shoulder joint.
Basically, adequate strength in the rotator cuff muscles helps to create balance. It is all in an effort to keep your shoulder as centered in the joint as possible.
Here’s what the researchers concluded:
1. EMG activity of the posterior deltoid was significantly greater with a neutral grip than with a pronated grip.
2. EMG activity of the infraspinatus was significantly greater with a neutral grip than with a pronated grip.
3. EMG activity of the middle deltoid was greater (but not statistically significant) with a neutral grip than with a pronated grip.

Here’s what a neutral grip looks like:
Here’s what a pronated grip looks like:
Although the study was only performed on the reverse fly machine, here is my suggestion- perform the exercises I detail in How To Keep Your Shoulders Healthy with a neutral grip.
For instance, instead of the pronated grip I use to demonstrate the Band Pullapart, use a neutral grip:
For the Cuban Presses or DB Cleans, use a grip like this:
Again, I’m drawing conclusions from this data, but I think that the suggestions I make are valid. So give this grip adjustment a shot. I hope it helps to keep your shoulders healthier this season.
