I am looking for some advice. I have been working a lot on weight and circuit training, trying to build some nice lean muscle and get more definition. However, I think I have a weak spot and I am not really sure how to fix it.
I think my shoulders are very weak. My core is pretty strong, and my arms are too, but I have a heck of a time doing exercises like pushups and anterior raises. I can hold plank for over 4 minutes, but after 12 pushups I collapse. And I can do most of the 30 day shred with 10 lbs weights, but when I do the side lunges with anterior raises, I have to do them with 2 lb weights and even then, my arms are shaking violently. Is there a specific muscle in there that would explain this weakness?
Do you have any ideas for what I can do to specifically target those muscles?
Thanks in advance!
