Dumbbell Prone Incline Hammer Curl
- Beginner
- Isolation
- Rep-based
- Upper arms
The prone incline hammer curl isolates the brachialis and brachioradialis by using the bench to eliminate momentum and body sway. This chest-supported position places the arms in front of the torso, emphasizing the thickness of the upper arm and forearm.

Setup
- Set an incline bench to an angle between 30 and 45 degrees.
- Lie face-down (prone) on the bench with your chest supported and your feet firmly on the floor for stability.
- Hold a dumbbell in each hand using a neutral grip (palms facing each other).
- Let your arms hang straight down toward the floor, fully extended and perpendicular to the ground.
How to do it
- Exhale as you curl the dumbbells toward your shoulders while keeping your elbows fixed in position.
- Maintain the neutral 'hammer' grip throughout the entire movement without rotating your wrists.
- Squeeze your biceps and forearms at the top of the contraction for a one-second pause.
- Inhale as you slowly lower the weights back to the starting position using a controlled 3-second eccentric tempo.
Form checklist
- Keep your chest glued to the bench to prevent using momentum or 'cheating' the weight up.
- Ensure your elbows stay pointed directly at the floor and do not drift forward or backward.
- Maintain a neutral wrist alignment; do not let the wrists cock back or curl forward.
- Achieve a full stretch at the bottom of each rep by fully extending the elbows.
Pro tips
- Focus on 'crushing' the dumbbell handles as hard as possible to maximize recruitment of the brachioradialis and grip stabilizers.
- Keep your chin tucked and neck neutral to avoid straining your upper traps during heavy sets.
Make it harder
- Incorporate a 2-second isometric hold at the midpoint (90-degree elbow flexion) of every repetition.
- Perform the eccentric (lowering) phase even slower, taking 5 seconds to reach full extension.
