The Best Bicep Exercises with Dumbbells for Strong Arms

When it comes to building strong, well-rounded arms, biceps are key players. Not only do they contribute significantly to arm aesthetics, but strong biceps also enhance functional upper-body strength. Whether you’re lifting, pulling, or carrying, your biceps are working. But if you’re aiming for noticeable arm development, focusing on your biceps with dumbbells can be a game-changer.

 

Dumbbells are a fantastic tool for bicep workouts. Why? They allow for isolated muscle activation, meaning you can zero in on each arm individually. This is great for fixing muscle imbalances and enhancing symmetry. Plus, the freedom of movement with dumbbells engages stabilizing muscles, making every rep more effective.

 

Warm-up routine for bicep workouts

A proper warm-up helps prevent injuries like strains or tears, and it primes your muscles for maximum engagement. You want your muscles to be supple and your joints to be ready for the strain that follows.

 

Here’s what you can do:

  • Light cardio: 2-3 minutes on a treadmill or jump rope to get the blood flowing.
  • Dynamic stretches: Arm swings, shoulder rolls, and chest openers.
  • Lightweight sets of curls: Grab a light set of dumbbells and perform 2 sets of 10 reps with controlled, slow movements.

Quick 5-Minute Warm-up Routine:

  1. 2 minutes of jump rope or brisk jogging in place.
  2. 15 arm swings (front to back).
  3. 15 shoulder rolls in both directions.
  4. 2 sets of 10 lightweight dumbbell curls with a slow, controlled tempo.

 

Now you’re ready to lift!

Best dumbbell bicep exercises

Let’s take a look at our favorite exercices: 

1. Dumbbell bicep curl (Standard)

The classic move that never gets old. The dumbbell bicep curl directly targets the biceps and is an essential exercise for building mass.

 

How to perform:

  • Stand tall with feet shoulder-width apart.
  • Hold a dumbbell in each hand with palms facing forward.
  • Curl the weights up towards your shoulders while keeping your elbows close to your body.
  • Squeeze your biceps at the top, then slowly lower the weights back down.

 

Tips:

  • Avoid using momentum (no swinging!); focus on isolating the biceps.
  • Keep your wrists straight throughout the movement.

2. Hammer curl

If you want thicker arms, the hammer curl is your go-to. It targets not only the biceps but also the brachialis and brachioradialis, helping you develop both width and forearm strength.

 

How to perform:

  • Hold dumbbells with a neutral grip (palms facing your body).
  • Curl the weights up while maintaining the neutral grip, keeping elbows close to your sides.
  • Lower slowly and repeat.

 

Benefits: Hammer curls add density and strength, especially in areas that standard curls may not fully activate. This move gives your arms that well-rounded, thick look.

3. Concentration curl

This exercise is all about isolation. Seated concentration curls allow you to focus solely on your biceps, leading to impressive muscle activation and sculpted definition.

 

How to perform:

  • Sit on a bench, lean forward slightly, and rest your elbow against the inside of your thigh.
  • Holding a dumbbell, curl it towards your shoulder with a controlled motion.
  • Pause and squeeze at the top before slowly lowering.

 

Why include it: If you’re looking to build peak bicep strength and maximize the shape of your biceps, this one’s for you. It’s a slow, focused move that targets the bicep heads.

4. Incline dumbbell curl

The incline dumbbell curl stretches the long head of the biceps more than a traditional curl, giving you that fuller appearance from top to bottom.

 

How to perform:

  • Set an incline bench to about 45 degrees.
  • Lean back with a dumbbell in each hand, palms facing forward.
  • Curl the weights up while keeping your elbows stationary. Lower the weights back slowly.

 

Key focus: Avoid flaring your elbows out. Keep the tension in your biceps throughout the entire movement by maintaining strict form.

5. Zottman curl

The Zottman curl is a power-packed combo that works both your biceps and your forearms in one smooth motion. You’ll supinate (rotate palms up) on the way up, and pronate (rotate palms down) on the way down.

 

How to perform:

  • Start with palms facing up as you curl the dumbbells up.
  • At the top, rotate your wrists so your palms face down, then lower the weights slowly.
  • Rotate palms back to the starting position at the bottom.

 

Why it’s effective: This movement trains both the biceps and the often-overlooked forearm muscles, boosting your grip strength and overall arm endurance.

6. Cross-body hammer curl

A hammer curl variation, this one targets your biceps and forearms while working in a slightly different plane of motion.

 

How to perform:

  • Hold a dumbbell in each hand with palms facing your body.
  • Instead of curling straight up, bring the dumbbell across your body towards the opposite shoulder.
  • Slowly lower and repeat on the other side.

 

Benefits: This variation increases brachialis engagement, helping to build thicker, stronger arms. It also gives your forearms some extra attention.
