How to Perform Dumbbell Curls

  1. Stand with feet shoulder-width apart holding dumbbells at your sides
  2. Keep your elbows close to your torso throughout the movement
  3. Curl the weights up by flexing your biceps
  4. Squeeze at the top of the movement for a brief pause
  5. Lower the dumbbells back down with a controlled tempo

Form Tips

  • Keep your upper arms stationary, only forearms should move
  • Don't swing the weights or use momentum
  • Supinate your wrists as you curl for maximum bicep activation
  • Control the negative portion, don't just drop the weight
  • Stand tall and avoid leaning back

Common Mistakes to Avoid

  • Swinging the body to generate momentum
  • Moving elbows forward or backward during the curl
  • Using too heavy a weight and sacrificing form
  • Rushing the eccentric (lowering) portion
  • Not achieving full range of motion
