Barbell Wrist Curl
- Beginner
- Isolation

- Upper arms
The Barbell Wrist Curl is a premier isolation exercise for developing the wrist flexors, enhancing both forearm hypertrophy and grip strength. It specifically targets the muscles on the underside of the forearm through a concentrated, short range of motion.

Setup
- Sit on the edge of a flat bench with your feet flat on the floor, shoulder-width apart.
- Grasp a barbell with an underhand grip (palms facing up), with hands spaced about shoulder-width apart.
- Rest your forearms on your thighs or across the flat bench, allowing your wrists to hang just over the edge.
- Ensure your elbows and wrists are in a straight line to prevent joint strain.
How to do it
- Inhale as you slowly lower the barbell by extending your wrists toward the floor, allowing the bar to roll down toward your fingertips.
- Exhale as you curl the barbell upward by flexing your wrists as high as possible while keeping your forearms pressed firmly against your thighs.
- Squeeze the forearm muscles at the top of the movement for a one-second peak contraction.
- Lower the weight with control using a 2-second eccentric (lowering) phase.
Form checklist
- Keep your forearms glued to your thighs or the bench; do not let them lift as you curl.
- Move only at the wrist joint, avoiding any 'body swing' or bicep involvement.
- Use a full range of motion, ensuring a deep stretch at the bottom and a full crunch at the top.
- Maintain a firm but controlled grip to ensure the bar doesn't slip during the finger-roll phase.
Pro tips
- To maximize muscle fiber recruitment, let the bar roll all the way to your distal phalanges (fingertips) at the bottom of the rep before curling back up.
- Focus on the mind-muscle connection by visualizing the muscles on the inside of your forearm shortening as you pull your palms toward your inner wrists.
Make it harder
- Implement a 3-second isometric hold at the peak of the contraction to increase time under tension.
- Use a 'Fat Grip' or wrap a towel around the barbell to increase the diameter, significantly increasing the demand on your grip.
