Dumbbell Preacher Curl
Dumbbell Preacher Curl targets the biceps in an isolating manner and helps build mass and peak in the upper arms. The bench support minimizes body movement and enhances the muscle feel.

Why Dumbbell Preacher Curl?
The Scott bench curl with dumbbells is an excellent and effective isolation exercise that directly targets the biceps. It allows you to significantly build upper arm mass and improve the so-called "peak" of the biceps, which is the muscle's apex. This exercise is particularly suitable for those who want to maximize bicep development and focus on pure muscle work without assistance from other muscle groups. The unique design of the Scott bench supports the arms and forearms, effectively eliminating body sway and assistance from the legs or back. This forces the biceps to do all the work and allows for extreme focus on muscle contraction and stretching. When the exercise is performed with dumbbells instead of a barbell, you can also correct imbalances and develop both arms evenly. Using dumbbells also provides a wider range of motion and better muscle feel, as you can slightly rotate your wrists at the top of the contraction. The exercise is intermediate level, meaning it requires some experience to master the correct technique, but it is easily learned. It is a great addition to a strength program or a workout aimed at muscle growth. When you want to ensure that your biceps receive the attention they deserve and develop maximally, the Scott bench curl with dumbbells definitely has a place in your training program. Focus on a slow, controlled execution and feel the muscle working with each repetition.

How to perform
Setup
- Adjust the Scott bench height so that your armpit rests comfortably against the pad and your upper arm is fully supported.
- Sit on the bench, lightly resting your chest against the pad and placing the working arm on the pad with the palm facing up.
- Grip the dumbbell with a neutral grip and rotate your wrist into a supinated position (palm facing you). Keep your upper arm in place and your shoulder blades slightly back and down.
Execution
- Inhale and lower the dumbbell in a controlled manner by extending your elbow until your elbow joint is nearly straight and you feel the stretch in your biceps.
- Hold a slight pause at the bottom position to maintain tension in the biceps.
- Exhale and curl the dumbbell up towards your shoulder by bending your elbow. Avoid overextending your wrist and moving your upper arm away from the pad. Tense at the top position for a moment and lower the weight down in 2-3 seconds. Repeat for the desired repetitions.
Coaching cues
- •Keep your elbow and upper arm firmly against the pad throughout the set.
- •The movement should come from the elbow joint; avoid swinging and assistance from the back.
Common mistakes
❌ Too heavy weight and poor control
Why it's wrong: When the weight is too heavy, the movement turns into swinging, and instead of targeting the biceps, the lower back and shoulders become strained. This takes power away from the target muscle and increases the risk of injury.
✓ Fix: Choose a weight that allows you to perform the movement in a controlled manner throughout the entire range of motion. Focus on the muscle contraction and stretching.
❌ Wrist bending or opening
Why it's wrong: If the wrists bend up or down, they become unnecessarily strained and can become sore. This also weakens grip and bicep activation.
✓ Fix: Keep your wrists straight and locked in line with your forearms throughout the movement. Imagine that the dumbbell is an extension of your arm.
❌ Incomplete range of motion
Why it's wrong: Performing the movement only partially, either by leaving the bottom position incomplete or the top position short, limits the muscle's full stretch and contraction, which weakens development potential.
✓ Fix: Lower the dumbbells in a controlled manner to nearly full extension (but not locked out) and raise them up so that the biceps fully contract. Feel the stretch and squeeze.
Frequently asked questions
Why is the Scott bench more effective than standing dumbbell curls?
The Scott bench effectively eliminates the assistance of other muscle groups, such as the back and shoulders, from the movement. The bench support forces the biceps to do all the work, allowing for cleaner isolation and deeper muscle feel. This helps focus maximally on bicep development.
How often should I do Scott bench curls with dumbbells?
The optimal frequency depends on your goals and the rest of your training program. For muscle growth, 2-3 times a week can be effective, as long as you give your muscles enough time to recover between workouts. Listen to your body and avoid overtraining.
Can this exercise be done without a Scott bench?
Similar isolation can be sought by sitting on an incline bench or leaning your arms against some support. However, these do not provide as sturdy support as the Scott bench, so the risk of cheating increases. The Scott bench is the best option for this exercise.
What is the difference between doing Scott bench curls with dumbbells and a barbell?
With dumbbells, you can correct imbalances and give both arms individual loading. It also allows for a more natural wrist movement and contraction at the top. With a barbell, you can generally use a larger total weight, but it ties your hands together and may highlight possible imbalances.
Safety tips
- Always start with light weights and focus on technique before adding weight.
- Keep your wrists straight and aligned with your forearms to avoid strain injuries.
- Do not fully extend your elbows at the bottom position – maintain slight tension in the biceps to protect the joints.
- Lower the weights in a controlled manner; avoid sudden, jerky movements.
- Adjust the bench height so that your upper arms rest comfortably against the bench and you achieve an optimal range of motion.
