I had golfers elbow really bad, and a few things have all but fixed it:
1) on the elbow it's hurting, look at wrist positioning, making sure you're not oddly over extending it or letting it roll over during lifts
2) high rep Curls. I'm talking 40+ rep sets, usually just use a barbell, reverse or regular grip. first few reps kind of will hurt a bit, but after that it starts to feel better. Idk, Paul Carter and Jim Wendler recommended it for elbow pain, 100 rep BB curls, and it worked. No idea why, just did
3) Voodoo bands, as the above poster said. Did wonders
4) Pulling exercises that hurt (my issue was vertical pulling mostly), use fat grips. Once again, not sure why, alleviated all pain for me.
Try any of this, hopefully it helps!
