Dumbbell Curl

Muscles Worked

How to Perform

1. 1

   Setup: Stand with feet shoulder-width apart, holding a dumbbell in each hand with arms fully extended. Keep your palms facing forward (supinated grip), shoulders back, and core engaged. Let the dumbbells hang naturally at your sides with elbows close to your torso.

2. 2

   The Curl: Keeping your upper arms stationary and elbows pinned to your sides, curl the dumbbells up toward your shoulders. Focus on contracting your biceps, not swinging with momentum. Exhale as you lift and maintain a controlled tempo for 2 seconds on the way up.

3. 3

   Peak Contraction: At the top of the movement, squeeze your biceps hard for a 1-second pause. Your dumbbells should be at shoulder level with palms facing your shoulders. Avoid bringing your elbows forward or letting them drift away from your torso.

4. 4

   Lower: Slowly lower the dumbbells back to the starting position under complete control. Take 3 seconds on the descent to maximize time under tension. Inhale as you lower and resist the weight—don't let gravity do the work. Fully extend your arms at the bottom.

5. 5

   Repeat: Maintain tension in your biceps even at full extension—don't completely relax or lock out. Keep your body still with no hip movement or upper body lean. You can curl both arms simultaneously or alternate for better mind-muscle connection.

Common Mistakes

• Using Momentum and Swinging

  Rocking back and forth or using your hips to swing the weight takes tension off the biceps. If you need momentum, the weight is too heavy. Keep your torso upright and still throughout the entire movement.

• Elbows Drifting Forward

  Letting your elbows move forward as you curl shifts tension from the biceps to the front delts. Keep your elbows locked in place at your sides—only your forearms should move during the curl.

• Incomplete Range of Motion

  Stopping short at the bottom or not fully curling to the top limits muscle growth. Always work through the full range—full extension at the bottom and a complete contraction at the top with dumbbells near shoulders.

• Lowering Too Fast

  Dropping the weight quickly wastes half of the exercise's growth potential. The eccentric (lowering) phase builds serious size—control the descent for 3 seconds and feel the burn in your biceps.

Pro Tips

• Add Extra Supination

  Start with a neutral grip (palms facing each other) and rotate your wrists outward as you curl. This supination engages more bicep muscle fibers, especially the short head, for better peak development and a stronger contraction.

• Try Alternating Arms

  Curling one arm at a time allows greater focus and mind-muscle connection on each bicep. You can also use slightly heavier weight since your core only stabilizes one side at a time, plus you can coach yourself through each rep.

• Pin Your Elbows Back Slightly

  Instead of keeping elbows at your sides, pull them back an inch behind your torso. This increases the stretch on your biceps at the bottom and prevents your front delts from taking over. Think "elbows behind your back."

• Visualize Bringing Pinky to Shoulder

  Focus on bringing your pinky finger to your shoulder rather than thinking about lifting the dumbbell. This mental cue ensures full supination and maximum bicep contraction, especially targeting the outer bicep for that coveted peak.
