I would like to inspire folks to think with this post. No specific questions that I need answered, just a question I would like to share to hear you guys beliefs on the topic.
I noticed that in 99% of shoulder routines you see in the magazines and on the internet, they involve 3 staple exercises. The shoulder press, the lateral raise, and the rear deltoid fly.
My question is why do we hammer our front delts (which get major stimulation when we flex at our shoulder, I.e every time we press) with shoulder presses and when it comes to medial and posterior deltoids we perform isolation movements. Why not hit the side deltoid with a compound exercise. I mean the medial deltoid laterally abducts the humerus, why do we think we need to keep our arms straight to do that?
This is true for every exercise that involves keeping the arm straight, all keeping a straight arm does is double the lever arm length making the exercise harder to progress. So why do we twittle away with lateral raises and rear delt fly (and straight arm pushdowns, and chest flies, and front raises) ?
