Ryan,
What exercises are you doing for your shoulders? Also, how many sets and reps are you doing for the shoulders per workout? You may not be loading your shoulders enough.

Hi Ryan, it may be a number of different reasons and I’d have to take a look at your form to be sure. You may be swinging or not coming down to 90 degrees elbow bend, or it could be simply that your arm muscles need to be strengthened so you don’t feel them as much. This might be a great reason for you to consult with a personal trainer.

Sam,
I’m new to strength training and am wondering how to really target shoulder muscles. Whenever I do pull-ups or shoulder presses, it seems like my shoulders aren’t doing anything and it’s all in my biceps or triceps. What am I doing wrong?
