TweetJust like the low back were you have a posterior chain connection and that makes you loosen the surrounding muscle to get relief, well the front delt is no different.

The major connection to the front delt is the Pectoralis Major Tendon Muscle, this is a twine of tendon and muscle from the area of the delt and chest.

So I find that when I take a lacrosse ball and roll the delt and pec major standing against a wall I get instant relief from my front delt and then do other stuff to loosen it like dislocations and wall stretches but these done without the rolling of the ball is not the same it's the ball that gives the greatest relief.

I use the same theory with low back and hip flexors, I loosen the low back my hips instantly loosen, I loosen my hamstrings my low back get instant relief.

So the moral to this is it may not be what you think it is and most likely never is, it's most likely a surrounding muscle or tendon your felling elsewhere.
