Bicep Curls on the lower block standing

Stand in front of the machine, holding the handle with one hand, as shown in the figure. Make sure that the shoulder is still and that the part of the arm from the shoulder to the elbow is perpendicular to the floor. Elbow near the body, palm facing forward. Place your free hand on the belt to maintain balance. Slowly exhale as you bend your arm for biceps. The part of the arm from the elbow to the shoulder must remain motionless. Tip: Only the forearm works. The movement should continue until the biceps is fully contracted, until the arm is at shoulder level. Take a short pause, tensing your muscles. As you inhale, slowly lower your arm to the starting position. Complete the required number of repetitions. Do the exercise with the other hand.
