Dumbbell Pronate-Grip Triceps Extension

  • Intermediate
  • Isolation
  • Rep-based
  • Chest
  • Upper arms

This isolation exercise targets all three heads of the triceps, with the pronated (overhand) grip providing a unique stimulus to the lateral and medial heads. It allows for a deep stretch at the bottom of the movement, maximizing muscle fiber recruitment through a focused range of motion.

Equipment

  • Dumbbell

Setup

  1. Lie flat on a bench with your feet firmly planted on the floor for stability.
  2. Hold a dumbbell in each hand directly over your chest with your arms fully extended.
  3. Rotate your wrists so your palms are facing toward your feet in a pronated grip.
  4. Position your upper arms so they are vertical or slightly tilted back toward your head to maintain constant tension.

How to do it

  1. Inhale and slowly lower the dumbbells by bending only at the elbows, bringing the weights down toward the sides of your forehead.
  2. Keep your upper arms stationary and tucked in throughout the entire descent.
  3. Exhale as you use your triceps to extend your arms back to the starting position, focusing on a strong contraction at the top.
  4. Maintain a controlled 3-second eccentric (lowering) phase and a 1-second concentric (lifting) phase.

Form checklist

  • Keep your elbows tucked in and avoid letting them flare out to the sides.
  • Ensure the movement occurs only at the elbow joint; the shoulders should remain locked in place.
  • Keep your lower back pressed against the bench to avoid arching.
  • Maintain a firm, pronated grip without letting the wrists collapse.

Pro tips

  • Focus on the mind-muscle connection by imagining you are pushing the weight away using only the back of your arms.
  • For maximum long-head activation, lower the dumbbells slightly past your ears to increase the stretch before extending.

Make it harder

  • Pause for two seconds at the bottom of the movement to eliminate momentum and increase time under tension.
  • Perform the exercise on a slight decline bench to further increase the range of motion and triceps recruitment.
