How can I effectively perform straight bar drag curls to target my biceps and improve my arm strength?

To effectively perform straight bar drag curls for targeting your biceps and improving arm strength, start by holding a straight barbell with an underhand grip. Keep your elbows close to your body and slowly lift the barbell towards your chest, focusing on squeezing your biceps at the top of the movement. Lower the barbell back down in a controlled manner. Perform 3-4 sets of 8-12 reps, ensuring proper form and technique throughout. This exercise can help isolate the biceps and promote muscle growth in the arms.
