About dumbbell alternate biceps curl

The dumbbell alternate biceps curl is a classic isolation movement designed to build the peaks and thickness of the upper arms. By curling one arm at a time, you can focus on the mind-muscle connection and prevent strength imbalances between sides. The ability to rotate the wrist at the top of the movement allows for maximum supination and bicep peak contraction.

Instructions for Proper Form

Setup:

  1. Position: Stand or sit on a bench with your back straight. Hold a dumbbell in each hand at your sides.
  2. Grip: Start with a neutral grip (palms facing your body).

The Movement:

  1. Curl (One Arm): Keeping your upper arm stationary, exhale and curl one dumbbell up towards your shoulder. As you lift, rotate your wrist so that your palm faces up (supination) at the top of the movement.
  2. Squeeze: Squeeze your bicep at the top.
  3. Lower: Inhale and slowly lower the dumbbell back to the starting position, rotating your wrist back to the neutral position.
  4. Alternate: As one arm returns to the start, begin the curl with the other arm.

Tips:

  • The supination (twisting) of the wrist is key to fully engaging the bicep muscle.
  • Avoid swinging the weights or using your back to help lift them.
  • Keep your elbows pinned to your sides.

Common mistakes: Swinging the body for momentum, not fully extending the arm, and rotating the wrists too late.

barbell wide grip curl

By gripping the barbell wider than shoulder width, you shift the focus of the curl toward the short (inner) head of the biceps. This variation helps add width to the upper arms and improves the overall shape of the muscle. It is a classic mass builder that requires controlled movement to maximize tension on the biceps while minimizing the use of momentum or shoulder involvement.
