Dumbbell Biceps Curls-Correct Form,Benefits and Muscles Used

Dumbbell biceps curls is an isolation exercise which helps to develop big biceps. It is a strength training exercise and involves a pair of dumbbells. There are plenty of variations in this exercise, each one targeting the biceps from a different angle. They will be covered later on.

Correct Form Of Dumbbell Biceps Curls


Here is a step-by-step description on how to execute the dumbbell biceps curls correctly.

  • Grab a pair of dumbbells and keep them by your side. Tuck your elbows in by your sides, and dont let the dumbbells touch your body. Keep a slight bend in your elbows and knees, and keep your shoulders back and chest out.
  • Many people like to hold the dumbbells with palms facing forward, while some like to hold them with palms facing each other. Whichever position you choose, becomes your starting position.
  • Slowly curl the dumbbells up without moving your elbows (OK, you might move them, but JUST a little bit) and contract and squeeze your biceps as you reach the top of the motion. Exhale while you do so.
  • Now slowly bring the dumbbells back to starting position, inhaling on the way down, till you reach the starting position. This completes one rep.

Precautions To Keep During Dumbbell Biceps Curls


There are a few precautions/tips that you must keep in mind while performing the dumbbell biceps curls.

  • Never swing the weights. If you cant lift it without your body swinging like a pendulum, choose a lighter weight.
  • Always choose moderate weights. Correct form is much more important than heavy weights here.
  • Keep your elbows fixed during the repetitions. Moving your elbows back and forth will put undue stress on your shoulders.
  • Do not let the dumbbells touch the body. The aim is to keep them under stress throughout the exercise. Resting them against your body will take that stress off them.
  • Keep the rep timing slow. Bring the dumbbell down slowly. The time to come down should be double than what it took to curl the weights up.
