could the elbow pain be also a result of heavy dips i think you do? preacher curls you have to do strict...emphasis on strict..people only get elbow problems on these because of bad form,too much weight. I have never had a problem with preacher curls. Maybe better using Dumbbells too so you can move a bit more freely.
well, i've had this elbow strain off and on for about 6 months now and i only started doing the dips about 6 weeks ago
i strained it before doing heavy db alternate curls and heavy db hammer curls
