How to Dumbbell Bicep Curl
Starting Position
1. Please stand shoulder-width apart.
2. Hold the dumbbells with your palms facing your body and position them next to your thighs.
3. Keep your chest up and your back straight.
Proper Form
1. Please lift the dumbbell while keeping your elbows and shoulders fixed.
2. As you lift, rotate your palms to face your body to maximize the contraction of your biceps.
3. Slowly return to the starting position.
4. When lowering the dumbbell, do not lower it completely; lower it just enough so that your biceps do not relax.
Breathing Technique
Exhale when you raise your arms, and inhale when you lower them.
Muscles Dumbbell Bicep Curl Works
Muscles used
- Bicepsfront of the upper arms
- Brachialisdeep muscle under the biceps near the elbow
- Brachioradialisouter forearm muscle running from the elbow toward the thumb side of the wrist
- Front deltsfront of the shoulders
Main muscleHold dumbbells at your sides and curl them toward your shoulders. As you turn your palms up, the main muscle driving the movement is your biceps. Your biceps bend your elbows and help rotate your forearms upward.
Supporting musclesYour brachialis helps bend the elbows, your brachioradialis supports the forearm and grip, and your front delts help keep the upper arms steady.
How it should feelAs the dumbbells rise, the front of your upper arms should shorten and squeeze. When your palms face up, your biceps contraction should feel clearer.
Signs you're offIf your elbows swing forward or your lower back leans back, you are using shoulders and momentum instead of biceps. Swinging the dumbbells reduces tension on the target muscle.
Remember thisKeep your elbows by your sides, turn your palms up, and curl with your biceps.
