The preacher curl locks the upper arms flat on an angled pad, which removes swing and keeps constant tension on the lower biceps. It is one of the strictest curl variations and builds strength through the stretched position.

📋 How To Perform Preacher Curl
1
Sit at the preacher bench with your upper arms flat against the pad.
2
Grip the bar (or dumbbell) with arms fully extended.
3
Curl up without letting your elbows lift off the pad.
4
Squeeze at the top, then lower slowly — don't let the weight drop.
5
Avoid locking out hard at the bottom to protect the elbow joint.
💡 Benefits of Preacher Curl
The angled pad locks the upper arms in place, so the biceps do all of the work with almost no momentum. It loads the lower part of the biceps strongly and is a useful way to build size without needing heavy weights.
📈 Sets, Reps & Programming
Do 3 sets of 8 to 12 reps with a moderate load, resting 60 to 90 seconds. Keep the armpits snug against the top of the pad and avoid fully locking out the elbows at the bottom, because the stretched position can stress the tendon.
⚠️ Common Mistakes to Avoid
Lifting the elbows or chest off the pad as the weight gets heavy
Dropping the weight fast and snapping the elbow straight
Using a grip so wide that the wrists strain
✅ Pro Tips
Stop a few degrees short of full lockout at the bottom to protect the elbow joint
Keep the shoulders relaxed and down; do not shrug toward the ears
🛡️ Safety Notes
The stretched bottom position puts stress on the biceps tendon. Avoid very heavy loads and bouncing out of the bottom if you have had a distal biceps injury.

Make it easierlower the weight and use a dumbbell for each arm separately.
Why does the preacher curl hurt the front of my elbow?
The deep stretch loads the biceps tendon. Reduce the weight, stop a little before full lockout, and lower more slowly. If pain persists, skip this exercise.
Is the preacher curl better than the standing barbell curl?
It is stricter and better for isolation, while the standing version allows heavier loads. Using both in a routine covers both goals.
