I had severe elbow pain while doing curls (and some other movements). At one point I was barely able to do 20s for 12 reps. If I laid off bicep curls, I could come back for a session and do 25s for a little while. Then I was back to having horrible pain.

2 weeks on prami has basically cured the elbow pain. It's the only change I've made.

I'm back up to using 50s for DBs and I feel almost no pain/discomfort.
