I've been following a bodyweight training routine for 2 months now and I'm satisfied with the gains until now.
I am training to improve how I look, and I've succeeded till now except for my shoulder. My collar bone is very visible and it makes me look very skinny despite being in a good shape.
Some people told me that my upper chest needs some workout. I don't know if it was true. So, what muscle do I have to train to make it less visible ?
Please, suggest some workouts for the upper chest if it was the muscle that I have to train. I do only bodyweight exercises.
