Typically I can curl 60-70 pounds for multiple sets with no problem using a regular grip.
When I do barbell reverse curls, I get some significant pain at the top of the rep in my right bicep. In particular I feel it close to my elbow. It's like painful twitch. I feel some discomfort build up throughout the rep and then when I get to the top, I get a very sharp twitch-like pain. My left arm is completely fine throughout the rep. I am left handed (idk if that matters or not).
When I do regular curls or hammer curls, I feel no pain at all in either bicep. As far as I can remember, I've never had any injuries to my right bicep.
When I grab a 20 pound ez curl bar and go super slow, I can do a rep without feeling pain, but I still feel a 'weirdness' or discomfort in my right bicep at the same location (near the elbow).
When I work out slow with light weight, I feel like I'm wasting my time. If try heavier weight, I can't make it through a set due to the pain.
Should I work through this with the light weight and see what happens? or Should I avoid this exercise and replace it with something else?
Thanks!
