Losing hip position during the Machine Preacher Curl shifts the loading pattern away from your Biceps brachii and can compress your lower back. Stay planted and let your Biceps brachii do the work.
Lifting off pad during curl.
On pulling movements like the Machine Preacher Curl, this mistake typically means your arms are doing work that should come from your Biceps brachii. Initiate every rep by engaging your Biceps brachii first, then let your arms follow.
Using momentum instead of controlled motion.
