Description
Stand tall with a dumbbell in each hand and arms at your sides, palms facing inward. Curl one dumbbell upward while rotating the palm to face up, keeping the elbow close to your torso and the upper arm still. Squeeze the biceps at the top, then lower the weight slowly while rotating the hand back to a neutral grip. Repeat with the opposite arm, alternating sides without swinging or leaning back.
How to Perform
- Stand tall with your feet about hip-width apart, holding a dumbbell in each hand at your sides with your arms fully extended and your palms facing your thighs.
- Brace your core, keep your chest lifted, and pull your shoulders gently down and back without arching your lower back.
- Keeping your upper arm close to your torso, curl one dumbbell upward while rotating your palm from neutral to facing upward as the weight rises.
- Continue lifting until the dumbbell is near shoulder height, squeezing your biceps at the top without allowing your elbow to drift forward excessively.
- Lower the dumbbell slowly and under control, rotating your palm back toward your thigh as your arm returns to full extension.
- Repeat the same movement with the opposite arm, alternating sides for the desired number of repetitions.
- Exhale as you curl and inhale as you lower, keeping your torso still and avoiding swinging, leaning back, or using momentum.

Tips
- Stand tall with your feet about hip-width apart, holding dumbbells at your sides with a neutral grip and your elbows close to your torso.
- Curl one dumbbell at a time while rotating your palm upward as the weight rises, finishing with the palm facing your shoulder.
- Keep your upper arm mostly still; only your forearm should move at the elbow during the curl.
- Squeeze your biceps briefly at the top without lifting your shoulder or allowing the elbow to drift far forward.
- Lower the dumbbell slowly and under control, rotating back toward a neutral grip as it returns to your side.
- Avoid swinging your torso, leaning back, or using momentum; reduce the weight if you cannot keep your body stable.
- Keep your wrist straight and aligned with your forearm rather than bending it backward or curling it toward your body.
- Exhale as you curl and inhale as you lower, maintaining a controlled tempo on both sides.
- Use a full comfortable range of motion, but do not force the elbow to lock out aggressively at the bottom.
- Choose a weight that allows smooth, even repetitions on both arms without twisting your hips or shoulders.
Common Mistakes
- Swinging the torso or using hip drive to lift the dumbbell
- Letting the elbow drift far forward or away from the side
- Curling the weight with the shoulder instead of isolating elbow flexion
- Failing to fully supinate the forearm as the dumbbell rises
- Bending or extending the wrist instead of keeping it neutral and aligned with the forearm
- Using only a partial range of motion and not lowering the dumbbell under control
- Dropping the dumbbell quickly during the lowering phase
- Shrugging the shoulder toward the ear during the curl
- Using a load that prevents controlled, alternating repetitions
