To perform a set of barbell wrist curl:
Sit on a bench with your knees bent and feet on the ground shoulder width apart. With your elbows bent and forearms resting on your thighs, hold a barbell with a supinated grip and let your hands drop toward the floor. Your trunk should be in a neutral position and your shoulders relaxed.
Without raising your elbows off of your thighs, curl your hands up and toward your trunk so your palms are facing you.
Pause at the top position for a 1 sec count while continuing to pull your hands toward your trunk.
Lower the bar down under control until your hands have dropped below your forearms toward the ground. Remember to breathe normally throughout the entire movement.
Repeat steps 1 through 4 until you have completed the desired number of barbell wrist curl repetitions before resting the barbell on the ground.
This completes one set of barbell wrist curl.
