Preacher Curl

Muscles worked

Main muscles
- Biceps Brachii (Long Head)
What it is
This isolation movement uses an E-Z curl bar and a preacher bench to intensely target your biceps brachii. You perform controlled curls, focusing on a deep stretch and powerful contraction through the full range of motion.
Technique tips
- Maintain full upper arm contact with the preacher pad.
- Keep your chest pressed firmly against the bench.
- Control the descent, slowly lowering for a deep stretch.
- Exhale as you curl the bar up, focusing on biceps contraction.
- Squeeze your biceps intensely at the top of each repetition.
- Avoid rocking your body; isolate the biceps movement.
How to track your progress
Log the weight and reps of each set. Straddly turns every set into an estimated one-rep max, so a heavier single and a strong set of eight both count as progress, and it flags a personal record the moment you beat your best.
