It is an exercise for arms and as its name indicates, the main muscle worked is the biceps, which is requested intensely because the bank does not allow us to help with the rest of the body or mobilize the arms.
Sitting on the machine, we rest all our arms on the desk of the scott bench and take some dumbbells with our hands, so that the palms face upwards. Without mobilizing the arms and with the same stretched out while we hold the weight, we begin the exercise.
Breathe in and start by bending your elbows to bring your hands to the chest next to the weight, breathe out at the end of the movement and return to the initial position slowly, without fully extending your arms.
