How to do dumbbell reverse grip biceps curl
Master the setup, range of motion, and tempo for safer, more effective reps.
Overview
Most arm training ignores the forearms, but the reverse curl changes that. By facing your palms down, you shift the load from the biceps to the brachialis and brachioradialis. This builds thickness in the upper forearm and helps 'push' the bicep up, making the entire arm look more complete and powerful.
Why Use It
- Builds significant forearm thickness and grip strength.
- Targets the brachialis to improve bicep 'peak' appearance.
- Balances out the elbow joint by strengthening the forearm muscles.
When to Use It
This is a perfect finisher for a pull day or arm session. Use it after your standard curls to fully exhaust the muscles of the arm.
Instructions for Proper Form
Setup
- The Stance: Stand with your feet hip-width apart and your core braced.
- The Grip: Hold the dumbbells with an overhand grip, palms facing your body.
- The Elbows: Tuck your elbows into your ribs and keep them there throughout the set.
Execution
- The Curl: Lift the weights toward your shoulders while keeping your knuckles pointing toward the ceiling.
Pro Tip: Keep your wrists 'stiff.' If your hands start to flop down, you're losing the tension in your forearms.
- The Squeeze: Pause for a split second at the top to feel the forearms and biceps contract.
- The Control: Lower the weights slowly. The descent is where most of the forearm growth happens.
Coaching Cues
- Knuckles to the ceiling
- Glue elbows to ribs
- Fight the weight down
Common Mistakes
- Ego Swinging: Using your hips to bounce the weight up because it's too heavy for your forearms.
- Wrist Collapse: Letting the wrists bend or 'flop' at the top of the movement.
- Elbow Drift: Letting the elbows swing forward to help lift the weight.
How to Fix It
- Ego Swinging: Drop the weight by 20% and focus on keeping your torso perfectly still.
- Wrist Collapse: Squeeze the dumbbell handles as hard as possible to keep the wrists locked in a straight line.
- Elbow Drift: Imagine your elbows are bolted to your ribcage and can only rotate, not move forward.
Mistakes by Level

Form Checklist
- Are your palms facing down throughout the rep?
- Are your elbows pinned to your sides?
- Are your wrists staying straight and strong?
Range of Motion
Curl from full arm extension to just below shoulder height.
Breathing Pattern
Exhale as you curl up; inhale as you lower the weights.
Tempo Guidance
3-0-1-0: Three seconds down to maximize the forearm tension.
Caution Notes
- Expect to use significantly less weight than a standard curl. Don't let your ego dictate the load.
Programming
Treat these guidelines as practical programming defaults, then scale load, volume, and frequency to match the rest of the training week.
Best For

Variations
Use progressions to increase difficulty when you master the movement, and regressions if you struggle with proper form or face mobility limitations.
Regressions
Hammer Curls
A neutral grip is stronger and easier on the wrists while still hitting the forearms.
Best for: Beginners.
Progressions
Fat Grip Reverse Curls
A thicker handle increases the demand on the grip and forearm muscles.
Best for: Advanced grip training.
FAQ
Common Questions
Why can't I lift as much as a regular curl?
The muscles on the back of your forearm are much smaller than your biceps. It's normal to lift about 30% less on this variation.
