If you are looking to get you those bulging biceps that you'll be dying to measure (and show off), the dumbbell curl is a great exercise. It's a common one but doing it correctly can mean the difference between results and injury.
Start with the biceps in a fully stretched position.
- Raise one arm at a time.
- Raise the arm until your bicep is in a fully flexed position with the hand at shoulder height, then lower the dumbbell with control, back into the start position.
*IMPORTANT NOTE: Wait until one arm is back in the start position before raising the other arm.
