The following article has alot of information on Biceps Tendinopathy, which include suggestions for the bench press:

Training with Biceps Tendinopathy • Stronger by Science

I'm not sure I'm understanding his suggestions under the "Mechanics and Variant Selection" section of the Bench Press. He mentions you can adjust things like grip width, elbow tuck, arch, etc. But outside of just pain being the indicator, what is it that you are trying to accomplish? Limit the ROM? That sounds like wider grip and bigger arch. But then he mentions specifically that excessively arching isn't helping. I alos know that generally people recommend narrowing your grip with shoulder issues. What am I missing. Can anyone reword it?
