So, I'd moved up to 4x9r on the Push Up, but scaled back to week 1 when I developed pain in my sternum. I then took a week off from the exercise, but upon resuming it, the pain came back. I have read the other threads on chostochondritis on this forum, but foam rolling and stretching have not helped relieve the discomfort.
The parts of the movement that cause pain are:
1 protracting the scapulae
2 externally rotating my shoulders, so that my elbow pits face forwards at the top of the push-up.
I did find that an initial flaw in my form was that my shoulders were a bit behind my hand at the top of the movement, but I'm not sure if that could have caused the injury.
Any and all help is appreciated. Thanks,
Aadil
