Performing the: A Step-by-Step Tutorial Cable One Arm Reverse Preacher Curl
Stand facing away from the machine, and grab the handle with an underhand grip (palm facing up) using one hand.
Position yourself in a staggered stance for stability, slightly bend your knees, and lean forward a bit from the waist, keeping your arm fully extended.
Slowly curl the handle up towards your shoulder, keeping your elbow stationary and only moving your forearm.
After reaching the peak contraction, slowly lower the handle back to the initial position, fully extending your arm, and repeat the movement for the desired number of repetitions.
