Cable Curl
The cable curl is an isolation exercise for the biceps performed with a cable machine and a straight bar or EZ-bar attachment. The constant tension provided by the cable makes it particularly effective for building arm size and strength.

How to do the Cable Curl
- 01
Attach a straight bar or EZ-bar to the low pulley of a cable machine.
- 02
Stand facing the machine with feet shoulder-width apart and grip the bar with an underhand, shoulder-width grip.
- 03
Keep your elbows tucked against your sides and your torso upright.
- 04
Curl the bar upward by flexing your elbows, keeping your upper arms stationary.
- 05
Squeeze your biceps at the top of the movement.
- 06
Lower the bar under control until your arms are fully extended.
- 07
Repeat for the desired number of repetitions.
Cues that matter
