Description

The Dumbbell Lying One Arm Press is a strength-building workout that primarily targets the chest muscles, with secondary focus on the triceps and shoulders.

How to Do Dumbbell Lying One Arm Press

  1. 1
    Setup

    Lie supine on a flat bench with your feet flat on the floor, providing a stable base and keeping your glutes and upper back in contact with the bench.

  2. 2
    Setup

    Hold one dumbbell in one hand, resting it on your chest with your elbow bent and tucked slightly towards your side, palm facing inward (neutral grip).

  3. 3

    Engage your core and press the dumbbell straight up towards the ceiling, fully extending your elbow without locking it, exhaling as you press.

  4. 4

    Slowly lower the dumbbell back down to the starting position with control, allowing your elbow to descend slightly below bench level to feel a stretch in your pectoral muscle, inhaling during the descent.

  5. 5

    Maintain stability throughout the movement, preventing your torso from rotating or lifting off the bench, and repeat for the desired number of repetitions before switching arms.

Tips

  • Keep your non-working arm extended out to the side or placed on your abdomen for balance and to prevent your torso from twisting during the movement.
  • Focus on driving the dumbbell up using your chest muscle, envisioning your pectoral contracting to initiate and complete the press rather than just pushing with your arm.
  • Control the eccentric (lowering) phase of the movement; this is crucial for muscle growth and maintaining tension on the chest throughout the entire range of motion.
  • Maintain a slight arch in your lower back, keeping your glutes and upper back firmly pressed against the bench for optimal stability and leverage.

Common Mistakes

  • ×Allowing your body to rotate or lift off the bench during the press compromises stability and reduces target muscle activation; keep your core braced and body still on the bench.
  • ×Rushing the eccentric phase reduces time under tension and potential muscle growth; ensure a slow, controlled descent of the dumbbell to maximize muscle engagement.
  • ×Pressing the dumbbell in an arc rather than a straight line can put undue stress on the shoulder joint; always press the dumbbell directly upwards in a vertical path.
