When I was doing a 5x5 based workout a year or so ago, I had issues when trying to push the weight on the overhead press. Even though the weight felt comfortable in the sense that I could do at least 5 reps with a minimum of a few sets, twice on separate occasions I pulled a muscle in my upper-back/neck which prevented me from working out again for 2-3 days before it healed.
I switched to doing seated press and haven't had an issue with it until recently. While doing a higher yet still comfortable weight on bench-press, I pulled the same muscle and am baffled as to how it could happen doing such an exercise.
My question is, what am I doing wrong on both exercises that could be putting so much strain in an area that isn't a main muscle for the workout (especially in the bp case)? And what could I change in my form to help prevent this?
I had a spotter on both instances, during ohp they didn't mention anything about my form being wrong, and I followed the head movement described for most ohp forms when lifting the weight up.
For bp, I arch my back and assume typical bp form.
Prevents me from turning my head left or right to the normal maximum degree without straining/pain in the pulled muscle area.
Below I've circled where I feel the most strain from the pull.
