An isolation biceps exercise using a cable machine and preacher bench. The supported upper arms and cable resistance keep the focus on elbow flexion and the biceps.
Adjust the preacher bench so that your upper arms rest comfortably on the pad with your elbows slightly bent.
Attach a straight or EZ-curl bar to the low pulley of a cable machine.
Sit on the preacher bench and grasp the bar with an underhand grip, hands shoulder-width apart.
Start with your arms fully extended, maintaining tension in the cable.
Curl the bar upwards by contracting your biceps, keeping your upper arms stationary against the pad.
Pause briefly at the top of the movement when your forearms are vertical and your biceps are fully contracted.
Slowly lower the bar back to the starting position, maintaining control and tension in your biceps.
Repeat for the desired number of repetitions.
Keep your back straight and avoid leaning forward during the curl to maintain proper form.
Focus on squeezing your biceps at the top of each curl for maximum contraction.
Use a controlled tempo; avoid swinging or using momentum to lift the weight.
Ensure a full range of motion by fully extending your arms at the bottom of each rep.
Start with a lighter weight to master form before progressing to heavier loads.
Maintain a firm grip on the bar to ensure stability and control throughout the exercise.
Lifting the upper arm or shoulder off the preacher pad.
Using momentum or bending the wrist to compensate for excess load.
Dropping the handle quickly and losing control near elbow extension.
