Preacher Curl

Muscles Worked

How to Perform

1. 1

   Setup: Adjust the preacher bench seat so that when you sit, your armpits rest on top of the pad and your arms hang naturally down the angled surface. Grip the handles or bar with an underhand grip at shoulder-width. Your chest should press firmly against the pad for stability.

2. 2

   Starting Position: Start with arms fully extended down the pad, but maintain a slight bend in your elbows to keep tension on the biceps—don't lock out completely. Keep your wrists straight and neutral. Take a deep breath and brace your core before starting the curl.

3. 3

   The Curl: Curl the weight up smoothly by flexing only at the elbows. Your upper arms remain completely flat against the pad throughout—no lifting or peeling away. Focus on squeezing your biceps hard as you curl. Aim to bring the weight to within 6 inches of your face at the top.

4. 4

   Peak Contraction: At the top, pause for 1-2 seconds and squeeze your biceps as hard as possible. Your forearms should be nearly vertical. This is where the exercise really shines—hold this contraction and feel the intense burn building in your biceps.

5. 5

   Controlled Negative: Lower the weight slowly over 3-4 seconds, fighting gravity all the way down. The preacher curl's unique angle makes the bottom portion extremely challenging—embrace this difficulty. Control the descent until your arms are nearly extended, maintaining constant tension. Never drop the weight or hyperextend your elbows.

Common Mistakes

• Lifting Elbows Off the Pad

  When the weight gets heavy, lifters often lift their upper arms off the pad to use momentum. This defeats the entire purpose of the preacher curl. Keep your triceps glued flat to the pad for the entire set—if you can't, the weight is too heavy.

• Dropping the Weight Too Fast

  The eccentric phase is brutal on preacher curls, especially at the bottom. Many people let the weight drop quickly to avoid the burn—big mistake. The stretch under load at the bottom builds the most muscle. Lower slowly and control every inch.

• Improper Seat Height

  If the seat is too low, you'll hunch over and lose tension. Too high, and you can't stabilize properly. Adjust so your armpits rest comfortably on top of the pad with arms hanging naturally. Good setup equals effective reps.

• Hyperextending at the Bottom

  Locking out completely at the bottom puts dangerous stress on your elbow tendons and removes tension from the biceps. Keep a slight bend in your elbows at full extension to maintain constant tension and protect your joints.

Pro Tips

• Use Single-Arm Variations

  Training one arm at a time allows greater focus and helps correct imbalances. You can also use your free hand to apply manual resistance or assisted reps at failure. Single-arm preacher curls deliver an insane pump and mind-muscle connection.

• Angle the Pad Differently

  If your machine allows, try the steeper side of the pad for a more vertical angle that emphasizes the peak contraction. The traditional angle targets the stretch position more. Use both angles in your training for complete bicep development.

• Perfect for Drop Sets

  The machine preacher curl is ideal for drop sets because you can quickly adjust the weight pin. Hit failure, immediately drop 20-30%, keep going until failure again. Repeat 2-3 times for an unforgettable bicep pump and serious growth stimulus.

• Focus on the Bottom Stretch

  The lengthened position at the bottom is where muscle damage occurs. Don't rush through it—pause for a full second in the stretched position before curling. This loaded stretch is scientifically proven to maximize hypertrophy in the biceps.
