How to do cable biceps curl (sz bar)
Master the setup, range of motion, and tempo for safer, more effective reps.
The cable biceps curl with an SZ bar is a fantastic isolation exercise for the biceps. The ergonomic shape of the SZ bar reduces strain on the wrists, while the cable provides constant tension throughout the curl. This movement allows for a focused pump and helps develop the peak of the biceps, making it an essential part of an arm-day routine for hypertrophy and improved muscle definition.

Instructions for Proper Form
Setup:
- Cable Machine: Stand facing a low-pulley cable machine.
- Attachment: Attach an SZ-curl bar (sometimes called an EZ-bar) to the low pulley.
- Grip and Stance: Hold the SZ-curl bar with an underhand grip (palms facing up) at shoulder-width or slightly wider. Stand tall with feet shoulder-width apart and core engaged.
- Body Position: Position yourself a few inches away from the machine so there's tension on the cable even with your arms extended.
The Lift:
- Initiate the Curl: Keeping your elbows tucked by your sides, curl the SZ bar up towards your shoulders.
- Peak Contraction: Squeeze your biceps at the top of the movement, holding the contraction briefly.
- Controlled Lowering: Slowly lower the bar back to the starting position, resisting the urge to drop or relax at the bottom.
Tips:
- Elbow Position: Ensure your elbows remain stationary and tucked close to your body throughout the movement.
- Slow and Controlled: Avoid using momentum. Focus on the contraction of your biceps.
- Full Range of Motion: Extend your arms fully at the bottom, but avoid hyperextending your elbows.
- Grip Width: Experiment with different grip widths to find what works best for you. A slightly wider grip emphasizes the short head of the biceps, while a narrower grip emphasizes the long head.
Common mistakes: Swinging the elbows forward and back, not fully extending the arms at the bottom, and using the lower back to curl the weight.
