Exercise guide

Dumbbell LU Raise

  • Intermediate
  • Isolation
  • Rep-based
  • Shoulders

The LU Raise is a full-range lateral raise that targets the entire shoulder complex, upper traps, and upper chest by moving through a complete 180-degree arc. This variation maximizes time under tension and improves overhead mobility by engaging the deltoids through their entire range of motion.

Equipment

  • Dumbbell

Setup

  1. Stand with feet hip-width apart and a slight bend in your knees for stability.
  2. Hold a pair of light dumbbells at your thighs with your palms facing forward (supinated).
  3. Retract your shoulder blades slightly and maintain a tall, upright posture with a braced core.

How to do it

  1. Raise the weights out to your sides in a wide, sweeping arc while keeping your palms facing forward throughout the lift.
  2. Continue the movement past shoulder height until the dumbbells meet directly over your head, exhaling as you reach the top.
  3. Lower the weights back to the starting position following the same wide arc with a controlled 3-second tempo.
  4. Inhale as the weights return to your sides, ensuring you do not let them rest against your thighs between reps.

Form checklist

  • Keep palms facing forward or slightly up to maintain external rotation and protect the shoulder joint.
  • Avoid using momentum or 'swinging' the weights from the hips to start the movement.
  • Keep your ribcage tucked and core tight to prevent the lower back from arching as the arms go overhead.
  • Maintain a very slight, fixed bend in the elbows; do not allow them to bend further during the lift.

Pro tips

  • Focus on 'reaching wide' toward the walls rather than just lifting up to maximize lateral deltoid recruitment.
  • At the peak of the movement, perform a slight shrug to fully engage the trapezius and stabilize the scapula.
  • Use significantly lighter weights than you would for a standard lateral raise to maintain perfect control through the full range.

Make it harder

  • Add a 2-second isometric hold at shoulder height during the descent of every rep.
  • Perform the exercise from a tall kneeling position to eliminate any potential leg drive or hip compensation.
