Description

A strength training exercise that targets the triceps muscles. It involves sitting on a bench and extending a dumbbell over your head.

How to Do Dumbbell Seated Bench Extension

  1. 1
    Setup

    Sit upright on a flat bench with your feet flat on the floor, holding one dumbbell with both hands, gripping the top end of one bell.

  2. 2
    Setup

    Extend the dumbbell straight overhead, fully straightening your arms, ensuring your elbows are close to your head and pointing forward. This is your starting position.

  3. 3

    Slowly lower the dumbbell behind your head by flexing your elbows, keeping your upper arms stationary and close to your ears. Inhale during this eccentric phase.

  4. 4

    Pause briefly at the bottom, then powerfully extend your elbows to push the dumbbell back to the starting overhead position, contracting your triceps. Exhale as you extend.

Tips

  • Maintain a neutral spine throughout the movement; avoid arching your lower back excessively by engaging your core.
  • Keep your elbows tucked in and pointing forward, preventing them from flaring out to the sides, which reduces triceps activation.
  • Control the eccentric (lowering) phase of the movement, taking 2-3 seconds to lower the dumbbell to maximize muscle tension and growth.
  • Focus on squeezing your triceps at the top of the movement for a peak contraction, ensuring full extension of the elbow.

Common Mistakes

  • ×Allowing your elbows to flare out wide reduces triceps engagement; keep them tucked close to your head throughout the exercise.
  • ×Swinging the dumbbell up using momentum rather than triceps strength decreases effectiveness; control the movement by focusing on muscle contraction.
  • ×Arching your lower back can strain the spine; engage your core and maintain a neutral spine by sitting tall.
