Performing the: A Step-by-Step Tutorial Cable Seated One Arm Concentration Curl
Sit on a bench or chair with your feet firmly planted on the ground, and your body slightly turned towards the machine, then grab the handle with your palm facing up.
Keep your elbow close to your body and slightly bent, then curl the handle towards your shoulder, ensuring your forearm is doing most of the work and your body remains stationary.
Hold the position for a moment when your bicep is fully contracted and the handle is at shoulder height, then slowly lower the handle back to the starting position.
Repeat the movement for the desired number of repetitions, then switch to the other arm.
