What you'll gain

Builds the lower bicep and creates a fuller arm shape.
Removes momentum so every rep loads the biceps directly.
Reinforces strict elbow-flexion mechanics for cleaner curls overall.

Step-by-Step Instructions

1
Set the preacher bench so the top pad sits just under your armpits with your chest pressed against it.
2
Grip the EZ bar at the inner-angled grips with your palms facing up and arms fully extended down the pad.
3
Curl the bar up toward your shoulders by bending only at the elbows, keeping your upper arms locked on the pad.
4
Squeeze the biceps hard at the top of the rep without letting the elbows drift forward off the bench.
5
Lower the bar slowly over 2 to 3 seconds until your arms are almost fully extended at the bottom.
6
Stop just short of full lockout to keep tension on the biceps, then curl back up for the next rep.

Common Mistakes

Pulling the elbows back off the pad to use the shoulders, which removes the isolation from the curl.
Letting the bar drop fast at the bottom and bouncing out of the stretch, which strains the elbow tendons.
Lifting the chest off the pad to swing the weight up, turning a strict curl into a partial cheat rep.
Cutting the range short at the top or bottom, missing the stretch and contraction that drive bicep growth.

About This Exercise

The EZ bar preacher curl locks the upper arm against an angled bench so the bicep does the work alone. With no swing or body english available, every rep is a clean stretch and contraction through the elbow. The EZ bar's angled grip is also more wrist-friendly than a straight bar, which is why this is one of the most-used isolation curls in any gym. For app and course content, the preacher curl is a hypertrophy-block staple. It's the curl variation people search for when they want bigger, fuller bicep peaks, and it's a clean teaching piece for showing strict form without momentum. Drop this clip into your arm-day library and pair it with a hammer curl and a cable curl to cover the full bicep coaching set.
