How to do band standing hammer curl
Master the setup, range of motion, and tempo for safer, more effective reps.
Overview
The 'Hammer' grip (palms facing each other) shifts the focus of the curl. While it still works the biceps, it puts a heavy emphasis on the brachialis (a muscle that sits under the bicep) and the brachioradialis (a major forearm muscle).
Using a band for this movement is particularly effective because the resistance is highest at the top of the rep, where these muscles are strongest. This exercise is essential for anyone looking to build 'width' in their arms and improve their overall grip strength for heavy lifts like deadlifts.
Why Use It
- Builds the brachialis, which can make the arms look wider from the front.
- Strengthens the forearms and improves grip stability.
- Neutral grip is often more comfortable for lifters with wrist or elbow issues.
When to Use It
This is a great secondary arm exercise. Use it after your standard curls or as part of a forearm-focused circuit.
Stats
Instructions for Proper Form
Setup
- The Anchor: Stand on the center of the band. The wider your feet, the harder the resistance will be.
- The Grip: Hold the band with your palms facing inward toward your body.
- The Stance: Stand tall with your core engaged and a slight bend in your knees.
Execution
- The Curl: Flex your elbows to bring your hands toward your shoulders.
Pro Tip: Keep your palms facing each other the entire time. Do not rotate your wrists!
- The Peak: Squeeze your forearms and biceps at the top of the movement.
- The Control: Slowly lower the band back to your sides. Ensure your arms go completely straight at the bottom.
Coaching Cues
- Imagine your arm is a hinge; only the forearm should move.
- Keep your wrists stiff like they are in a cast.
Common Mistakes
- Rotating the Wrists: Turning the palms up at the top, which turns it into a regular bicep curl.
- Elbow Flare: Letting the elbows point out to the sides instead of staying tucked.
- Short-Changing the Bottom: Not letting the arms go fully straight, which reduces the work on the forearms.
Mistakes by Level
Beginner
- Using momentum to swing the band.
- Letting the wrists collapse.
Intermediate
- Moving the shoulders forward at the top of the rep.
Advanced
- Rushing the tempo to finish the set.

Form Checklist
- Are your palms still facing each other at the top?
- Are you swinging your elbows forward?
- Are you standing tall without leaning back?
Range of Motion
Curl from full arm extension until your thumbs are near your shoulders, then lower slowly.
Breathing Pattern
Exhale as you curl up; inhale as you lower down.
Tempo Guidance
1 second up, 1 second squeeze, 2 seconds down.
Caution Notes
- Avoid 'flicking' your wrists at the top; keep them neutral and strong.
Programming
Treat these guidelines as practical programming defaults, then scale load, volume, and frequency to match the rest of the training week.
Best For
- Building arm thickness.
- Improving grip and forearm strength.

Variations
Use progressions to increase difficulty when you master the movement, and regressions if you struggle with proper form or face mobility limitations.

Reduces the tension of the band.
Best for: Beginners.
Progressions
Top-Half Pulses
Performing small reps at the top of the range where tension is highest.
Best for: Advanced hypertrophy blocks.
FAQ
Common Questions
Does this work the same muscles as a regular curl?
It works the biceps, but it emphasizes the brachialis and brachioradialis (forearm) much more than a standard palm-up curl.
