What are some good alternative stretches for improving extension in the spine, for back bends, without aggravating the tendonitis in my triceps? Stretches like the box bridge cause too much stress on my elbow and triceps on my right arm. Any kind of pressing movement will give me a slight pain in my elbow. "Ex. 2 backward bending from the floor", only works if I press mostly with my left arm, and only add the support of my right when I can fully extend both arms. With the elbows on the floor I still feel a pain in my elbow. Passive backbends over a support do not cause pain though I feel as if I either am doing the exercise wrong, thus feeling no stretch, or I need to make it more intense. The rehab process is going great and its getting better. I just don't want to put any undo stress on my elbow. Also, I don't want to lose time working on my upper back for the sake of my elbow.
If needed, I can explain with a video to illustrate the issue.
