Hi there,
When I do lat pull downs with a pronated grip I occasionally get a ‘catching’ or pinching feeling kind of in my right biceps or under the right biceps, not sure what muscle it is.
If I lock out (straighten) my arm the pinching is about 3 inches up from where my biceps tendon joins my forearm.
If I use a neutral grip for lat pull downs or pull ups, I get no issues… but the pinching limits my training & yard work.
It only affects my right biceps.
Any idea what this is & how to fix it? Thanks all
